UnderCover FX21033 Flex Hard Folding Tonneau Cover Ford Ranger 24-25 5'1"
UnderCover Flex
Rugged, hard tri-fold tonneau cover designed to protect truck cargo with a low-profile folding design, secure hard-shell construction, and strong weather resistance.
The UnderCover Flex uses rigid, lightweight aluminum-skinned panels that are impact-, abrasion-, and cut-resistant. The panels are finished in a corrosion-resistant gloss-black texture for durable protection and sleek styling. When evenly distributed, the cover supports up to 400 lb.
Access is fast and simple: drop the tailgate, pull a release cable, and fold the cover toward the bulkhead. The cover can be secured in a 2/3 open position with integrated safety straps or folded flush against the rear window and held with built-in prop rods for full bed access. Close and lock the tailgate to secure your cargo.
The cover resists moisture with EPDM rubber hinges, perimeter seals, and a dual-action tailgate seal. Any water that passes the side seals is routed through integrated drain channels and out through drain tubes to keep the bed dry.
