UnderCover Flex tonneau covers leave other types of folding tonneau covers far behind! These Flex covers feature a sleek, low-profile look that fits flush with the bed rails and folds flat to allow easy access to the entire cargo area. Plastic buckles and straps secure the FRP panels in the partially open position, or use the built-in support rods to secure the covers, allowing your truck to be driven with the covers fully open. These Flex covers are made from an advanced fiberglass-reinforced polymeric material. They are UV resistant and feature rubber seals and weather-resistant drain tubes to channel water away from your truck bed and away from it. UnderCover Flex covers install easily in minutes, with no drilling required, and can be removed in seconds, with no tools required.
