The UnderCover Flex is a hard folding truck bed cover that gives you the ultimate control of your truck bed, offering three secure riding positions. The cover is easy to remove, requires no drilling for installation, and is mounted flush with your trucks bed rails making it the most watertight hard folding cover on the market. Each panel is made of high quality FRP composite material; which is lighter, stronger and more dent resistant than aluminum. Each Flex has a bed rail mounting system equipped with rubber seals and drain tubes that carry water away from and out of the bed, keeping your gear dry and secure. The Flex is backed by a 3-year warranty making it America's favorite hard folding tonneau cover.
