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.

The Flex truck bed cover is made from fiberglass reinforced panels with an aluminum frame. UnderCover chose to go with this type of panel since they are stronger, lighter, and very resistant to dents or scratches.

UnderCover has also added prop rods to hold your cover in the upright, folded position which allows you to use the full truck bed. The folding section can even be removed without any tools if you are hauling a load you need to keep an eye on. 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.
