Gator FX3 Hard Folding Tonneau Truck Bed Cover 2004-2013 Chevy Silverado GMC Sierra  5.8 FT Bed Fits Only - Gator FX3 Hard Folding Tonneau Truck Bed Cover 2004-2013 Chevy Silverado GMC Sierra 5.8 FT Bed Panels constructed of aluminum with an FRP coating on top EPDM seals provide maximum water resistance Fiberglass Reinforced Polymer exterior panel stays cooler to the touch and will not fade Made in the USA - 2 Year Warranty The Gator FX3 features the perfect blend of two materials: Fiberglass reinforced polymer top panels and aluminum sub-panels. The aluminum provides structure and rigidity while the fiberglass reinforced polymer protects against scratches and dents, while staying UV resistant. One of the best features the FX3 offers is the ability to gain full bed access. Simply use the pull cable from either side of the bed to disengage the slam latches, and fold the cover, panel by panel, to the front of the bed. The cover can be secured with 2/3 bed access using buckle straps, and driven down the highway. Also can lean it against the cab and secure it with the prop rods that are mounted to the rails. The rubber bumpers will keep the cab of the truck protected when the cover is opened fully. . EPDM seals and hinges provide great water resistance Holds 300lbs evenly distributed across the cover Slam latches automatically lock when closed Flush Hinge System Gator FX3 is designed to be consumer-friendly. Rail guides automatically set the height and direction of the side rails so the cover looks just like a professional mounted it. You can look at many other tonneau covers but you will be hard pressed to find anything that looks as good, functions as well, or is as durably constructed
