UnderCover Flex Hard Folding Bed Cover for 2021-2025 Ford F-150 & Lightning (5.5ft Bed) - FX21029

Fits select 2021-2025 Ford F-150 and F-150 Lightning models with a 5.5ft bed.

The UnderCover Flex (FX21029) is a hard folding truck bed cover that balances the security of a locking hard cover with the accessibility of a soft roll-up. Built from Fiberglass Reinforced Plastic (FRP) composite panels, this cover provides superior dent resistance and strength compared to traditional aluminum panels while remaining lightweight and easy to operate.

The ultra-low profile design sits inside the bed rails for a clean, flush aesthetic. When you need full bed access, the built-in prop rods secure the cover in a vertical position, allowing you to drive with the bed fully open. For hauling large items that require an unobstructed bed, the entire assembly can be removed in seconds without the use of tools.
