2017-2025 Ford F250 & F350 Undercover Flex Tri-Fold Tonneau Cover 6.8ft Short Bed | FX21021

Ergonomic Tri-Fold Design For The Bed Of Your Super Duty

One of the biggest problems with most of the folding tonneau cover designs out there is that they can be a pain to completely remove from your truck and practically require a full uninstall. That's why the engineers at Undercover designed the Flex Tonneau Cover to be an ergonomic solution to help you load and haul extremely large hardware and gear with minimal amounts of hassles. The Undercover Flex Tonneau cover is a bit different than Undercover's usual lineup and features a tri-fold design that flips up toward your Super Duty's cab to give you access to the bed. Even though it's a bit more complex than Undercover's other tonneaus, the Flex series is extremely strong and lightweight, making it easy to use while being durable enough to handle just about any application. The Undercover Flex Tonneau Cover is water resistant and comes with both seals and plumbing to keep your bed and all of its contents high and dry.

Easy, No-Drill Installation

The Flex Tonneau cover was carefully designed to outclass other fold-up tonneau designs by being easier to use while just as strong, durable, and dependable as Undercover's other tonneau options. The Flex cover is made out of interlocking, hinged panels that are each manufactured out of fiber-reinforced polymer plastic that's just as strong as aluminum while being more resistant to denting. The Flex Tonneau Cover has an extremely low-profile design that sits almost perfectly flush with your Super Duty's bed. When fully open, the tonneau is held up by both a built-in prop rod and buckle straps to keep it firmly in place when your bed is loaded down. The Flex Tonneau Cover is easy to install using a simple clamp and rail system and requires absolutely no drilling, cutting, or other permanent modifications to your truck.
