UnderCover Flex - Main Image


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. The Flex is constructed with heavy-duty FRP panels providing more strength, durability and dent resistance than aluminum panels.


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.
