Opinion

OPINION ON REHEARING

ELSA ALCALA, Justice.

We issued an opinion in this case on May 3, 2007. Appellee, Daryl Davis, moved for a rehearing. After receiving a response from appellant Ranger Conveying & Supply Company (“Ranger”), we grant rehearing, withdraw our opinion, vacate our judgment of May 3, 2007, and issue this opinion in its stead.

Ranger appeals a judgment, entered in accordance with the jury’s verdict, in favor of Davis, in the amount of $1.6 million for injuries Davis received when a 580-pound bale of paper pulp fell from a clamp truck owned by Davis’s employer, the Pasadena Paper Company (“Pasadena Paper”). The falling bale hit Davis’s arm and pinned his hand to a spike on a conveyor that was manufactured by Ranger. After Davis presented his case-in-chief, Ranger moved for an instructed verdict, which the court denied. The jury found Ranger liable for a marketing defect. Ranger moved for a new trial and for judgment notwithstanding the verdict (JNOV), but the trial court denied the motions.

In its third issue, Ranger contends that the trial court erred by denying Ranger’s motion for JNOV because “Ranger did not owe or breach any duty to Davis” or owe a duty to Pasadena Paper “to formulate facility policies.” We conclude that Ranger had no duty to warn about the interface area of Pasadena Paper’s clamp truck and Ranger’s conveyor because (1) the jury determined that there was no design defect in the conveyor itself, which was what Ranger was hired to design, produce, and install, and (2) the interface area was part of the larger system that included the loading of bales with the use of the clamp truck, and Ranger was not hired to and did not participate in the integration of the conveyor into the larger system. We reverse and render a take nothing judgment in favor of Ranger. 1

Background

Davis worked for Pasadena Paper for 12 years, and had worked in the hydropulper department for several months. The purpose of the hydropulper department is to convert large bales of raw material into pliant material that can be pressed into sheets of paper. Before the installation of the conveyors manufactured by Ranger, Pasadena Paper employees lifted bales one at a time into the hydropulper machine after cutting the wires from the bales.

To increase productivity by allowing more bales to be processed by the hydro-pulper, Pasadena Paper contracted with Ranger to design, manufacture, build, and install conveyors. The purchase order called for “two [20-inch] spiked chain de-wiring conveyors, with support, drive, motor starter, safety stop cable on both side[s], each designed to support 8 bales at 580 [pounds per] bale.” In December 1998, Ranger installed the conveyor that was involved in this incident, a 20- to 25-foot-long conveyor that moved a bale from one end, after the bale was placed onto the conveyor by a clamp truck, to the other end, where the bale was deposited into the hydropulper. The design of the Ranger conveyor included spikes to hold the bale up and away from the conveyor’s surface so that employees could more easily cut and remove the wire that surrounded the bale before it entered the hydropulper. Each bale was large, weighing approximately 580 pounds, and measuring 32 inches wide by 32 inches deep by 16 to 18 inches high. Each bale was bound by wire that needed to be cut off before the bale entered the hydropulper.

A clamp truck moved the bales of paper pulp throughout the plant. The bales were usually in stacks of six, because they arrived on trains stacked that way. When the clamp truck moved the stack of six bales, it used vertical clamps to grasp the bottom three bales to lift the entire stack of six bales, which left the top two to three bales unrestrained by the clamp.

Using the Ranger conveyor, four employees worked together as a crew to move bales into the hydropulper. One employee operated the clamp truck to lift a stack of six bales to transport them to the end of the conveyor. The stack was then placed onto the end of the conveyor. Once on the conveyor, the clamp truck operator moved the clamp apparatus to hold the second through fourth bales, thus allowing the bottom bale to be released and carried down the conveyor. This process was repeated until the entire stack of bales was placed on the conveyor. As the bales worked their way down the conveyor, one employee would cut the wire binding, while another employee pulled off the wire. A fourth employee would operate controls to move the conveyor forward so that the bales would be dropped into the hydropul-per vat.

On the night of November 2, 1999, Davis’s job was to cut the binding wire as the bale moved from one end to the other end of the conveyer. When the clamp truck brought a stack of six bales to the end of the conveyor, it set one bale down, and moved the clamps to clasp the second through fourth bales. The first bale had already been moved up the conveyor to approach the position where its wires would be removed. The second bale had not yet been placed onto the conveyor. When the accident occurred, both the clamp truck and the conveyer were stopped. The top bales that were stacked on the clamp truck, but were not held by the clamps, fell.

Davis was standing at the designated place for cutting wires, which was about one-and-one-half to two feet from the conveyor. Davis tried to spin away to avoid the falling bales, but one hit him, impaling his hand on one of the conveyor’s spikes. Davis was taken away by ambulance and began an arduous course of medical treatment. .

After Davis’s injury, changes were made to prevent a similar accident. The operator of the clamp truck was immediately instructed to lift only three bales at a time while loading bales onto the conveyor. About a week after Davis’s injury, Pasadena Paper had a cage installed between the clamp truck and the conveyor to block bales from falling from the clamp truck onto the conveyor. The cage was not attached to the conveyor, but instead was mounted to another structure. The cage has successfully prevented further injuries from faffing bales.

Ranger did not place warning labels on the conveyor system telling workers to avoid the area at the interface of the conveyor and clamp truck due to the faffing hazard, nor did it provide Pasadena Paper with instructions or warnings that employees should be kept away from that area. Additionally, Ranger did not provide Pasadena Paper with an operator’s manual. Warren Pearson, Ranger’s employee who sold the conveyor to Pasadena Paper, acknowledged that he did not provide any safety documents or safety sheets with the conveyor, even though he occasionally provides those documents to people who are going to be using conveyors sold by Ranger. Ranger was not asked to provide, and did not provide, any information or training to the workers who were going to be working on the conveyor system.

At trial, the parties disputed whether Ranger was asked to design a conveyor that was to be loaded with bales one at a time, or in stacks of six by use of a vertical clamp truck. According to Ranger, Pasadena Paper requested a conveyor that was to be loaded with bales one at a time. Pearson testified that his understanding was that Pasadena Paper would load bales one at a time with a clamp truck, and that it was never the plan for six bales in a vertical stack to be loaded onto the convey- or at once. After the conveyor was installed, Pearson examined the conveyors in use at the plant. Pearson testified that he observed bales lined up horizontally on the conveyor, but never saw bales vertically stacked on the conveyor.

Scott Collier, a Ranger employee, was the draftsman that designed the conveyor. Collier testified that he did not see the purchase order, but acknowledged that if he had seen the purchase order for a 25-foot conveyor, it “would have brought to attention some type of vertical orientation of the bales, which would have included some other framework or something for safety versus just the conveyor itself’ and he would have designed a safety derice to incorporate that vertical association of bales. Collier denied knowledge that a clamp truck was going to be loading the conveyor.

Davis’s expert, William Purcell, who specializes in safety engineering, testified that the problem with the conveyor was that there was a possibility that a bale could slip and fall at the interface between the clamp truck and the conveyor. The “problem with the way Ranger designed” the conveyor, according to Purcell, was that “when the load comes in, that — that it’s possible that a load might fall, might slip in the interfacing between the forklift and the conveyor. It could be — and that’s a hazard. That’s a foreseeable hazard, that bale could actually fall and then possibly even strike somebody when it fell.” Purcell testified that the conveyor did not meet the standards for conveyors set forth in the American Society of Mechanical Engineers (ASME) and Occupational Safety and Health Administration (OSHA) regulations.

In contrast to Ranger’s testimony, Davis contended at trial that Ranger was informed that the bales would be loaded onto the conveyor by the clamp truck in stacks of six. Tuan Nguyen, Pasadena Paper’s senior project engineer, ordered the conveyor from Ranger after discussing his desires for the project with Pearson, Ranger’s salesman. Nguyen explained that his requirements for the conveyors that he ordered were that he wanted the spiked conveyors to hold each bale up from the conveyor’s surface so that the wires that surrounded each bale could more easily be removed by the workers. According to Nguyen, the plan was for the clamp truck to bring a vertical stack of bales to the conveyor, then the clamp truck would drop each bale on the conveyor until five or six bales were lying across the convey- or. The workers would not move in until the stack of five or six bales were laid across the conveyor. The workers would then cut the wires from all the bales that were lying across the conveyor, and then the bales would all be moved into the hydropulper at once. Nguyen testified that he described to Pearson “the entire process” of transporting pulp bales, from removing them from the rail cars to placing bales on the end of the conveyor. Nguyen said that Pearson came to the plant to see the operation in progress, which would have included observation of the vertical stacking if the conveyor was in operation. Nguyen denies that he ever told anyone at Ranger that only one bale at a time would be set on the end of the conveyor “[bjecause that would defeat the whole purpose of the conveyor, because that’s what we were doing before the conveyor. Grab one bale, set it on top of the Hydropulper, pull the wire, dump.” Nguyen’s testimony was supported by Noel Spinks, a plant employee, who said that it was never their procedure to place one bale at a time on the Ranger conveyor. Spinks, who was working near Davis on the night Davis was injured, said that employees were “told we had to use a full stack to be able to keep up with the production machine.”

Nguyen approved the drawings of the conveyor design, inspected the conveyor after it was built, and accepted it. Nguyen personally looked at the conveyor and felt it was safe, as did Pasadena Paper’s safety and quality division.

Pasadena Paper acknowledged that it was responsible for training employees to use the conveyor. Bayless, a supervisor at the plant, and Spinks each testified that workers at the plant were trained on the operation of the conveyors by supervisors. Spinks, however, said that employees were not warned about the danger of falling bales near the conveyors. The Ranger conveyors were already being used by the hydropulper department when Davis started working in that department, and Davis said that he received “no training whatsoever” on how to operate the conveyors.

Ranger acknowledged that it was responsible for designing a safe conveyor, and it contends that it complied with that request by installing the emergency stop cord on the conveyor. According to Frank Loeffler, an expert who testified for Ranger, the conveyor produced by Ranger was “a standard conveyor” that had been used for many years. Loeffler explained that Ranger does not have the expertise to advise a paper company how to use a clamp truck or how to deliver a product onto the conveyor belt. According to Loeffler, Ranger did not agree to provide extraneous safety features that were not actually part of the conveyor. He also specifically testified that there was no agreement for Ranger to install a bale guard.

At trial, the evidence showed that after Ranger installed the conveyor, but before the incident involving Davis, Pasadena Paper made additions and changes to the Ranger conveyor system. Pasadena Paper added a three-foot square concrete pad, which is where Davis was standing during the accident. The pads were installed for shorter workers in order to make it easier to reach and cut the binding wires. Pasadena Paper also installed a barrier guard to protect the conveyor from trucks running into it, as well as foot control pedals to run the conveyor. No evidence in the record shows that Ranger participated in any of these changes.

Davis sued Ranger for negligence and strict products liability, alleging both a design defect and a marketing defect. The jury found in favor of Davis on the marketing defect issue and for Ranger on the design defect and negligence issues. The jury answered affirmatively that there “was a defect in the marketing of the Ranger Conveying equipment at the time it left the possession of Ranger that was a producing cause of the occurrence or injury in question[.]” 2 The jury’s failure to find any design defect in the conveyor that was the producing cause of Davis’s injuries has not been challenged on appeal by Davis.

Duty to Warn of Danger at the Interface Area

In its third issue, Ranger contends that the trial court erred by denying Ranger’s motion for JNOV because “Ranger did not owe or breach any duty to Davis under the facts of this case” or “to [Pasadena Paper] to formulate facility policies.” Ranger explains that “[t]he alleged hazard arose from [Pasadena Paper’s] operations and not from a risk of harm inherent in the product.” According to Ranger, the hazard “arose from [Pasadena Paper’s] practice of utilizing a clamp truck to lift more bales than could be supported by the clamps of the truck” and not from the “conveyor [that] operated the way it was intended to operate.” Ranger explains,

There is and should be a distinction between a conveyor and a company’s system of transporting goods throughout a facility. Unquestionably, Ranger would be involved in the safety of the conveyor. However, [Pasadena Paper] determined and controlled the conveyor system which included multiple stages.

Ranger cites to USX Corp. v. Salinas, 818 S.W.2d 473, 482-83 (Tex.App.-San Antonio 1991, writ denied) to support its assertion that the hazard arose from the operations at the plant and not from a risk of harm inherent in the product. 3

A. Preservation of Error

In his motion for rehearing, Davis contends that Ranger did not preserve the issue of what he characterizes as the “component-parts defense” for appeal. Davis contends that (1) Ranger failed to plead the defense and (2) under the Texas Supreme Court’s recent decision in Equistar Chemicals, L.P. v. Dresser-Rand Co., 240 S.W.3d 864 (Tex.2007), Ranger’s general JNOV was insufficient to preserve the component-parts issue.

Davis asserts that the component parts defense is an affirmative defense and as such, must be pleaded or it is waived. Davis cites to no authority that states that the component-parts defense is an affirmative defense. In contrast, Texas cases discuss the liability of a component-parts manufacturer in terms of duty. See Brocken v. Entergy Gulf States, Inc., 197 S.W.3d 429, 437 (Tex.App.-Beaumont 2006, no pet.) (“The Brockens failed to show that Cooper, a component-part manufacturer, under these facts and circumstances, had a duty to warn Entergy of the dangers of using a recloser for the special purpose that the Brockens assert Entergy used it.”) (emphasis added); Toshiba Int’l Corp. v. Henry, 152 S.W.3d 774, 783 (Tex.App.-Texarkana 2004, no pet.) (“Toshiba had no duty to the Henrys because it did not participate in the integration of its component part into the scrap winder system.”) (emphasis added).

Whether a duty exists is a question of law for the courts. See Humble Sand & Gravel, Inc. v. Gomez, 146 S.W.3d 170, 181 (Tex.2004). In other words, an assertion of lack of a legal duty is not an affirmative defense because:

The burden is on a plaintiff to prove the existence and violation of a legal duty owed by the defendant in order to establish tort liability. Coleman v. Hudson Gas & Oil Corp., 455 S.W.2d 701, 702 (Tex.1970). Lack of duty is not an affirmative defense because duty is an essential element of a plaintiffs case. Id.

Toles v. Toles, 113 S.W.3d 899, 909 (Tex.App.-Dallas 2003, no pet.). Because the component parts issue goes to the existence of a duty, it is not an affirmative defense that must be pleaded. See id. Thus, Ranger’s failure to plead that it was a component parts manufacturer cannot be the basis to find that it failed to preserve the issue as Davis contends.

Davis further asserts that the recent supreme court opinion in Equistar Chemicals shows that Ranger failed to preserve the component parts issue for appeal. In Equistar Chemicals, the defendant, Dresser-Rand, appealed a jury verdict in favor of the plaintiff, Equistar. Equistar Chemicals, 240 S.W.3d at 866. On appeal, Dresser-Rand contended that its no-evidence objections to the damages question and its motion for JNOV were sufficient to preserve error on the grounds that the economic loss rule precluded Equistar’s recovery. Id. The supreme court noted that Dresser-Rand only objected to the jury charge regarding damages on no-evidence grounds. Id. at 865. Dresser-Rand did not object to the damages question or instruction as submitted, and thus waived any error. Id. at 868. The supreme court cited to Texas Rule of Civil Procedure 274, which states, in pertinent part, “A party objecting to a charge must point out distinctly the objectionable matter and the grounds of the objection. Any complaint as to a question, definition, or instruction, on account of any defect, omission, or fault in pleading, is waived unless specifically included in the objections.” Tex.R. Civ. P. 274; Equistar Chemicals, L.P., 240 S.W.3d at 868. Further, the supreme court noted that even if the no-evidence points raised by Dresser-Rand necessarily encompassed the contention that no tort duty was owed under the facts of the case, the question as to how much damages, if any, Equistar could recover was an issue that “existed in the suit independent of the tort issues and questions.” Equistar Chemicals, at 868. However, the supreme court expressly withheld deciding whether a general no-evidence objection covered the contention “that [Dresser] owed no tort duty under the facts [of this case].” Id.

In contrast, in this case, the no-evidence point did not concern a jury question. Further, the no-evidence challenge here was only to the existence of duty, which is a question of law for the court. The component parts issue did not remain an issue in the case independent of Ranger’s challenge, as the issue of damages remained in Equistar Chemicals. See id. at 868. As noted in our original opinion, a “no-duty” challenge may be preserved by a motion for JNOV. See Chavez Constr., Inc. v. McNeely, 177 S.W.3d 593, 598 (Tex.App.-Houston [1st Dist.] 2005, pet. granted, pet. dism’d by agr.); Battaglia v. Alexander, 93 S.W.3d 132, 140 (Tex.App.-Houston [14th Dist.] 2002), rev’d on other grounds, 177 S.W.3d 893 (Tex.2005). In its motion for JNOV, Ranger asserted that it “did not owe or breach any duty to [Davis] under the facts of this case.” In addition, unlike Dresser-Rand in Equistar Chemicals, who did not identify the economic loss rule before the trial court, Ranger specifically asserted that it was not liable as a component parts manufacturer. Specifically, in moving for an oral instructed verdict at the close of all of the evidence, Ranger asserted as grounds:

All the evidence in this case has been that this conveyor was a component part of a larger system. The Supreme Court in — I can’t think of the case name, but it’s within the last six months — has decided that the manufacturer of a non-defective component part is not strictly responsible to the plaintiff for any injuries that he suffered because of a defect in the system.

Because the facts of this case are distinguishable from those in Equistar Chemicals and because Ranger expressly asserted the component parts doctrine to the trial court, we conclude that Ranger has preserved this issue for our review. See Chavez Constr., Inc., 177 S.W.3d at 598 (holding that “general no-evidence-of-negligence” ground asserted in motion for new trial preserved question of no duty for appellate review).

B. Products Liability and Component Parts

In order to recover for an injury on the theory of products liability, the plaintiff bears the burden of proving that (1) the defendant placed a product into the stream of commerce; (2) the product was in a defective or unreasonably dangerous condition; and (3) there was a causal connection between that condition and the plaintiffs injuries or damages. Houston Lighting & Power Co. v. Reynolds, 765 S.W.2d 784, 785 (Tex.1988); Armstrong Rubber Co. v. Urquidez, 570 S.W.2d 374, 376 (Tex.1978). However, “the law of products liability does not guarantee that a product will be risk free, since most products have some risk associated with their use.” Caterpillar, Inc. v. Shears, 911 S.W.2d 379, 381 (Tex.1995).

A product may be unreasonably dangerous due to a defect in its manufacture (manufacturing defect) or design (design defect), or because of a failure to provide adequate warnings or instructions (marketing defect). Am. Tobacco Co. v. Grinnell, 951 S.W.2d 420, 426 (Tex.1997); Caterpillar, 911 S.W.2d at 382; Turner v. Gen. Motors Corp., 584 S.W.2d 844, 847 (Tex.1979). Here, the jury found a marketing defect. A marketing defect is proven when the evidence shows that a defendant fails to warn of a product’s potential dangers, when warnings are required, and that the lack of adequate warnings or instructions renders an otherwise adequate product unreasonably dangerous. See Lucas v. Tex. Indus., Inc., 696 S.W.2d 372, 377 (Tex.1984); Benavides v. Cushman, Inc., 189 S.W.3d 875, 881 (Tex.App.-Houston [1st Dist.] 2006, no pet.) (citing Grinnell, 951 S.W.2d at 426). The elements of a marketing defect cause of action are (1) a risk of harm must exist that is inherent in the product or that may arise from the intended or reasonably anticipated use of the product, (2) the supplier of the product knows or reasonably should foresee the risk of harm at the time the product is marketed, (3) the product has a marketing defect, (4) the lack of instructions or warnings renders the product unreasonably dangerous to the ultimate user or consumer of the product, and (5) the failure to warn or instruct causes the user’s injury. Olympic Arms, Inc. v. Green, 176 S.W.3d 567, 578 (Tex.App.-Houston [1st Dist.] 2004, no pet.).

A component part manufacturer who does not participate in the integration of the component into the final system or product is not hable for defects in the final system or product if the. component itself is not defective. Bostrom Seating, Inc. v. Crane Carrier Co., 140 S.W.3d 681, 683 (Tex.2004); Molina v. Kelco Tool & Die, Inc., 904 S.W.2d 857, 861 (Tex.App.-Houston [1st Dist.] 1995, writ denied) (“A component part manufacturer that supplies a product in accordance with a purchaser’s specifications is free from strict liability if the component part itself is not defective.”). 4 For a duty to warn to be imposed on a component-part manufacturer or seller, it must have “actively participated in the integration process.” See Henry, 152 S.W.3d at 783 (citing Restatement (ThiRd) of Toets: Produots Liability § 5 (1998)); see also Bostrom Seating, 140 S.W.3d at 685 (“Crane was in total control of the design of [the restraint] system, and Bostrom, playing no part in the design of the truck, cannot be held liable for its possible defectiveness.”); Molina, 904 S.W.2d at 861.

Bostrom Seating and Henry both cite to and rely on the Restatement (Third) of Torts. Bostrom Seating, 140 S.W.3d at 683; Henry, 152 S.W.3d at 783. The Restatement provides:

One engaged in the business of selling or otherwise distributing product components who sells or distributes a component is subject to liability for harm to persons or property caused by a product into which the component is integrated if:

(a) the component is defective in itself, as defined in this Chapter, and the defect causes the harm; or

(b)(1) the seller or distributor of the component substantially participates in the integration of the component into the design of the product; and

(b)(2) the integration of the component causes the product to be defective, as defined in this Chapter; and

(b)(3) the defect in the product causes the harm.

Restatement (ThiRd) of Torts: Products Liability § 5. The comments and reporters’ note to section 5 clarify the extent of liability that is based on a failure to warn. A component seller has a “duty to supply reasonable instructions and warnings to the component buyer.” Id. cmt. b. Additionally, “the duty is to warn only immediate buyers and not to warn users of integrated final products.” Id. cmt. b Reporters’ Note. Finally, the Restatement acknowledges that components may “function on their own but still may be utilized in a variety of ways by assemblers of other products” or may “include products that can be put to different uses depending on how they are integrated into other products.” Id. cmts. a, d. In that case, a “safety feature important for one adaptation may be wholly unnecessary or inappropriate for a different adaptation.” Id. cmt. d.

C. Analysis

As noted in our original opinion, Ranger designed, produced, and installed the conveyor that was undisputedly a component of the plant’s larger bale-handling system that was composed of the clamp trucks that loaded the bales onto the conveyor itself, at one end, and the hydropul-per that processed the de-wired bales, at the other end. In his motion for rehearing, Davis contends that this Court erred by characterizing the conveyor as “undis-putedly a component of the plant’s larger bale-handling system.” (Emphasis added). Specifically, Davis contends that “Ranger’s conveyors stood alone and that their only purpose was to act as conveyors.” In support of this contention, Davis relies on the following testimony:

• Purcell testified that the conveyor “was a component of a larger operation” and was “part of a larger process” of putting pulp bales into the hydropulper. Purcell also testified:

The operation that goes on there at the conveyor is de-wiring. The conveyor itself does nothing but receive material and move the materials horizontally. That is all the conveyor does. It does not de-wire. The people do the de-wiring. It’s just — it receives material and moves it horizontally into where — until it drops into the Hydropulper.

• Pearson testified that the conveyors were intended to be “just part of a process that they were instituting to get bales into the hydropulper.” However, he also referred to the conveyors as the new “system” installed at the plant.

• Loeffler characterized the “system” at Pasadena Paper’s plant as beginning with unloading bales from rail cars and ending with completed paper. He specifically stated that the conveyor is “just a component piece of an overall system.” However, he also testified that “[t]he new system was two brand new conveyors.”

Davis also identifies Purcell’s testimony that an interface is “where two pieces of equipment come together” and that the clamp truck and the conveyor had to interface as further support that the conveyor is not a component.

Davis further attempts to distinguish the cases cited in our original opinion to show that the conveyor was not a component part. In Bostrom Seating, the component was a driver’s seat that was integrated into a garbage truck. 140 S.W.3d at 683. In Molina, a die was incorporated into a press. 904 S.W.2d at 859. In Toshiba International Corp., the defendant manufactured an inverter — a device that converted and regulated power flow — that was incorporated into the control panel of a larger machine. 152 S.W.3d at 777. In Buonanno v. Colmar Belting Co., Inc., a wing pulley was integrated into a convey- or. 733 A.2d 712, 714 (R.I.1999). Davis is correct in pointing out that in each of these cases, the component was a part of a larger final machine or product, and not, like the conveyor, a product in and of itself. Davis, however, fails to distinguish other cases cited in the original opinion with facts analogous to this case, in which the injury results from the interface of the product with other equipment.

In our original opinion in this case, we cited to Cipollone v. Yale Indus. Prods., Inc., 202 F.3d 376, 379 (1st Cir.2000) (applying Massachusetts law), which was cited favorably by the supreme court in Bostrom Seating. See Bostrom Seating, 140 S.W.3d at 683. In Cipollone, the component was a “customized dock lift” that was integrated into a “material-handling system.” Cipollone, 202 F.3d at 378 (emphasis added). The court applied the Restatement (Third) of Torts, section 5, to the dock lift — a complete product in itself. Id. at 379. In addition, in Brocken, a recloser (a circuit breaker) was installed as a part of a utilities’ electrical distribution system. 197 S.W.3d at 432. Further, in Davis v. Komatsu America Industries Corp., also cited favorably by the supreme court in Bostrom Seating, the defendant manufactured a press that was incorporated into an assembly line made up of various stages, including multiple individual presses and a conveyor. 42 S.W.3d 34, 36-37 (Tenn.2001). The Tennessee Supreme Court adopted and applied section 5 of the Restatement (Third) of Torts, although the press was a completed product and part of an assembly line. Id. at 35. Thus, contrary to Davis’s assertions, courts have applied the component parts doctrine to components, complete in and of themselves, that function as part of a larger “system.” See also Zaza v. Marquess and Nell, Inc., 144 N.J. 34, 675 A.2d 620, 626-27 (N.J.1996) (citing draft of Restatement (Third) of Torts and applying component parts doctrine to tank that was “component part for an integrated manufacturing system” for decaffeinating coffee beans).

As a component part manufacturer, Ranger has no duty to warn of dangers unless (1) the component itself is defective or (2) it actively participated in the integration of the component into the final system. See Bostrom Seating, 140 S.W.3d at 683-84; Molina, 904 S.W.2d at 861; Restatement (ThiRd) of ToRTS: PRoducts Liability § 5.

The jury answered “No” in response to the design defect question in the charge. Thus, the jury did not find that a design defect in the conveyor was the cause of Davis’s injury, despite the failure to attach a guard at the interface area to prevent the vertical stack of bales from falling on the conveyor. Davis has not challenged the jury’s verdict that there was no design defect in the Ranger conveyor that was the cause of his injuries. As a component part manufacturer, Ranger had no duty to warn of dangers of a non-defective component. See Bostrom Seating, 140 S.W.3d at 683 (holding that, because no evidence showed that seat was defective and seat manufacturer did not participate in integration of seat into truck design, seat manufacturer was not liable for defect in truck); Henry, 152 S.W.3d at 784 (holding no duty to warn of potentially dangerous condition caused by integration of non-defective component into system designed by another); Molina, 904 S.W.2d at 861 (holding that component-part manufacturer not strictly liable where evidence established that component part met specifications and was integrated into larger unit before distribution). 5

Because the component itself was not defective, Ranger only had a duty to warn if it actively participated in the integration of the component into the final system. See Bostrom Seating, 140 S.W.3d at 683; Molina, 904 S.W.2d at 861. No evidence shows that Ranger actively participated in the integration of the conveyor into the larger conveyor system. The evidence is undisputed that Ranger was not hired to and did not participate in the design, production, or installation of the larger system of transporting bales at the plant, which included the use of the clamp truck and the ultimate deposit of the bales into the hydropulper. The evidence is undisputed that Ranger was hired only to design, produce, and install the conveyor itself.

Davis contends that Ranger is liable for failure to warn of the dangers at the interface area because Ranger “knew or should have known of the danger posed by bales stacked at the end of the spiked conveyor.” The interface area, however, was not part of the conveyor itself, but was part of the larger system that included the loading of bales with the clamp truck. Davis described the interface area in his brief as follows:

The risk was in the interface between the clamp truck with its stack of bales and the spiked conveyor. More specifically, the danger was that a worker’s hand could be punctured in one side and out the other by a spike in the conveyor if a bale were to fall during loading.

According to Davis, the interface area is the area where the clamp truck meets the conveyor, but that area was undisputedly part of the larger bale-handling system that included the clamp truck. As Ranger points out, Ranger had no duty to warn of the interface area because that was a hazard that arose from Pasadena Paper’s practice of utilizing a clamp truck to lift more bales than could be supported by the clamps of the truck and not from the “conveyor [that] operated the way it was intended to operate.” See Crossfield v. Quality Control Equip. Co., 1 F.3d 701, 703-04 (8th Cir.1993) (holding no liability for failure to warn because no evidence showed that component “malfunctioned or failed to perform as intended”).

Cases from other jurisdictions have applied section 5 of the Restatement (Third) of Torts in analogous situations. See Cipollone, 202 F.3d at 379 (applying Massachusetts law); Buonanno, 733 A.2d at 716. In Cipollone, Cipollone filed suit against Yale, alleging that there was a defect or unreasonably dangerous condition in a loading dock lift that Yale manufactured. Cipollone, 202 F.3d at 378. Yale manufac tured the lift as specified by Cipollone’s employer, FedEx, and the lift was made a part of a larger package-handling system that FedEx designed with an outside consultant. Id. After Cipollone was injured, he alleged that the narrow spacing between the lift and an adjacent catwalk created an unreasonably dangerous condition. Id. The trial court granted summary judgment for Yale. Id. The court, citing section 5 of the Restatement (Third) of Torts, noted that a dock lift that was integrated into a larger package-handling system was a product that “function[s] on [its] own but still may be utilized in a variety of ways by assemblers of other products.” Id. at 379 (quoting Restatement (Third) of TORTS: PRODUCTS LIABILITY § 5 Cmt. a). The court affirmed the summary judgment in favor of Yale because there was no evidence that the lift was defective and it was “merely a component of FedEx’s larger package-handling system.” Id.

In Buonanno, Buonanno was injured when his arm was caught in a “nip point” 6 of a large conveyor. 733 A.2d at 713. Buonanno brought suit against Emerson Power Transmission Corporation, and others, alleging a defect in the conveyor and the wing pulley. Id. The wing pulley was a component part of the nip point that was manufactured by Emerson Power. Id. at 714. The trial court rendered summary judgment for Emerson Power, and Buo-nanno appealed. Id. at 715. After discussing the provisions in the Restatement (Third) of Torts for liability of a component part manufacturer, the court adopted section 5 of the Restatement. Id. at 716. The court noted that there was no evidence that Emerson Power participated in the design of the conveyor system, but only supplied the wing pulley. Id. at 717. Therefore, Emerson Power could not be hable under section 5(b) of the Restatement (Third) of Torts. See Restatement (ThiRd) of ToRts: Products Liability § 5(b). The court then examined whether the wing pulley was “defective in itself,” as required to support liability under section 5(a). See Restatement (Third) of Torts: Products Liability § 5(a). Under the Restatement, a defect must exist “at the time of sale or distribution.” Buonanno, 733 A.2d at 717 (quoting Restatement (Third) of Torts: Products Liability § 2 (1998)). The court noted that “the nip point is created only when the belt meets the wing pulley after the entire conveyor belt system is assembled.” Id. Therefore, the court concluded that Emerson Power could not be hable on that basis. Id 7

Here, Ranger manufactured a conveyor. Like the lift in Cipollone, it is a product that can be put to different uses depending on how it is integrated into other products. See Cipollone, 202 F.3d at 379; Restatement (Third) of Torts: Products Liability § 5 cmt. d. Because a product hke the conveyor can be used in a variety of ways, a “safety feature important for one adaptation may be wholly unnecessary or inappropriate for a different adaptation.” Restatement (Third) of Torts: Produots Liability § 5 cmt. d. For example, a warning about falling bales would not be necessary if the conveyor was used as part of a system that transported bales without stacking them. Further, hke the nip point and wing puhey in Buonanno, the dangerous condition alleged by Davis — the “interface” — did not exist until the Ranger conveyor was integrated into Pasadena Paper’s bale-handling system. See Buonanno, 733 A.2d at 717; see also Restatement (Third) of Torts: Products Liability § 2 (defect must exist “at the time of sale or distribution”); Bostrom Seating, 140 S.W.3d at 683 (holding that “if the component-part manufacturer does not participate in the integration of the component into the finished product, it is not liable for defects in the final product if the component itself is not defective”) (citing Restatement (Third) of Torts: Products Liability § 5); Brocken, 197 S.W.3d at 436 (applying principles of Bostrom Seating and the Restatement to marketing defect case); Henry, 152 S.W.3d at 783 (same).

We conclude that Ranger had no duty to warn of the larger system because no evidence shows that it actively participated in the integration process. See Bostrom Seating, 140 S.W.3d at 683; Molina, 904 S.W.2d at 861. Ranger had no duty to warn of the dangers at the interface area because the conveyor was a component of the larger bale-handling system; the jury did not find a defect in the conveyor itself; and Ranger did not actively design or participate in the integration of the conveyor into the larger system that included the loading of bales with a clamp truck. See Bostrom Seating, 140 S.W.3d at 683; Henry, 152 S.W.3d at 783; Molina, 904 S.W.2d at 861. Further, Ranger did not design the “interface.” See USX Corp., 818 S.W.2d at 487 (“It is a fundamental principle of products liability law that the plaintiff must prove that the defendant supplied the product which caused the injury.”) (citing Gaulding v. Celotex Corp., 772 S.W.2d 66, 68 (Tex.1989)). Thus, the evidence is legally insufficient to support the jury’s finding of a marketing defect. See Bostrom Seating, 140 S.W.3d at 683; Henry, 152 S.W.3d at 783; Molina, 904 S.W.2d at 861. As the jury found no design defect in the product and no negligence on behalf of Ranger, no liability theory supports the verdict.

We sustain Ranger’s third issue.

Conclusion

We reverse and render judgment that Davis take nothing from Ranger.

1 . Ranger presents six additional issues in this appeal that we do not reach. In its first issue, Ranger contends that the trial court erred by rendering judgment in favor of Davis and by denying Ranger's motion for JNOV because there was no evidence to support the jury’s finding that there was a marketing defect of the Ranger conveyor at the time it left the possession of Ranger that was a producing cause of the injury or occurrence. In its second issue, Ranger contends that the trial court erred by rendering judgment in favor of Davis and by denying Ranger’s motion for JNOV because “as a matter of law, the alleged danger was open and obvious.” In its fourth, fifth, and sixth issues, Ranger contends that the trial court erred by denying its motion for leave to file an amended answer to include the issue of comparative negligence and refusing to instruct the jury regarding comparative negligence and "sole cause.” In its seventh issue, Ranger asserts that "the trial court erred in denying Ranger’s Motion for New Trial because there was factually insufficient evidence to support the jury’s findings of a market defect and causation.”

2 . The charge defined "defect in marketing” as "a failure to give adequate warnings of the Ranger Conveying equipment’s dangers that were known or by the application of reasonably developed human skill and foresight should have been known, or a failure to give adequate instructions to avoid such dangers, which failure rendered the conveyor unreasonably dangerous as marketed.” The charge also defined " '[ajdequate' warnings and instructions” as "warnings and instructions given in a form that could reasonably be expected to catch the attention of a reasonably prudent person in the circumstances of the conveyor’s use; and the content of the warnings and instructions must be comprehensible to the average user and must convey a fair indication of the nature and extent of the danger and how to avoid it to the mind of a reasonably prudent person.” The jury charge further defined an "unreasonably dangerous” product as a product "that is dangerous to an extent beyond that which would be contemplated by the ordinary user of the conveyor with the ordinary knowledge common to the community as to the conveyor’s characteristics.”

3 . USX Corp. was a marketing defect case involving an oil rig elevator. USX Corp. v. Salinas, 818 S.W.2d 473, 477 (Tex.App.-San Antonio 1991, writ denied). USX was the retailer of an oil rig package that included an elevator. Id. The plaintiffs were injured when the elevator collapsed because of a defective hydraulic cylinder that was part of the elevator. Id. at 477-78. Before the elevator collapsed, the hydraulic cylinder was replaced with a cylinder purchased from a retailer and manufacturer other than USX. Id. at 485. USX contended that because it had no part in manufacturing or marketing the replacement cylinder, it could not be liable for a marketing defect. Id. at 487. In discussing the issue, the court emphasized that "[i]t is a fundamental principle of products liability law that the plaintiff must prove that the defendant supplied the product which caused the injury.” Id. (citing Gaulding v. Celotex Corp., 772 S.W.2d 66, 68 (Tex.1989)).

4 . Bostrom Seating was a design defect case. Bostrom Seating, Inc. v. Crane Carrier Co., 140 S.W.3d 681, 682 (Tex.2004). Kelco was a case involving claims for design, manufacturing, and marketing defects. Molina v. Kelco Tool & Die, Inc., 904 S.W.2d 857, 861 (Tex.App.-Houston [1st Dist.] 1995, writ denied). Other courts have applied the same principle to marketing defect cases. Brocken v. Entergy Gulf States, Inc., 197 S.W.3d 429, 436 (Tex.App.-Beaumont 2006, no pet.); Toshiba Int’l Corp. v. Henry, 152 S.W.3d 774, 783 (Tex.App.-Texarkana 2004, no pet.).

5 . In addition, the conveyor itself had sharp spikes emanating from it that were open and obvious, and, thus, Ranger had no duty to warn about those spikes. See Caterpillar, Inc. v. Shears, 911 S.W.2d 379, 382 (Tex.1995) (holding that there is no duty to warn of obvious risk associated with front-end loader that had open cab without safety cage); Joseph E. Seagram & Sons, Inc. v. McGuire, 814 S.W.2d 385, 388 (Tex.1991) (holding that there is no duty to warn of dangers of excessive or prolonged use of alcohol since these dangers are already so widely recognized); Hagans v. Oliver Mach. Co., 576 F.2d 97, 102 & n. 5 (5th Cir.1978) (after noting "obvious” dangers of table saw, stating that "a warning of the dangers involved in using the saw would not have informed [the plaintiff] of anything he did not already know”).

6 . "A 'nip point’ is created where the conveyor belt moves over the stationary portion of the conveyor-belt system, or the 'wing pulley.' The wing pulley prevents waste materials from getting caught between the roller and the belt.” Buonanno v. Colmar Belting Co., Inc., 733 A.2d 712, 713 n. 1 (R.I.1999).

7 . Ultimately, the court found that summary judgment was improper because a fact issue existed on other theories of liability presented to the trial court. Id. at 717.
