Undercover Flex


Low Profile, Full Bed Access, Easy Removal, Secure Design, FRP Panels, Weather Resistant, No Drill Installation, 3 Year Warranty.



The rails of the Undercover Flex are designed to rest inside the bed rails giving the Flex a very low profile appearance. Most hard tonneau covers don’t allow you full bed access without removing the whole cover. The Undercover Flex can be folded all the way up to the cab and held in place with Prop Rods. The cover can be removed with no tools in just seconds. If you need only a portion of the Flex Tonneau Cover open you can secure it with built in buckles and straps so that it won’t move while driving. Each of the three panels is constructed of Fiberglass Reinforced Polymer which is more durable than aluminum and gives it a higher load capacity. Undercover warrants the FRP structure of your Flex Cover to be structurally free from defects in material and workmanship for three years from the purchase date.
