Build Your Truck in 3D with RealTruck Builder
For ultimate cargo protection, you can’t beat a rugged, hard tri-fold bed cover, like the UnderCover® Flex from RealTruck®. The premium truck bed cover offers a robust and secure hard-shell construction, easy-to-use folding design, low-profile aesthetic, and exceptional weather resistance, protecting your truck bed in all conditions.
The UnderCover Flex Tonneau Cover features rigid yet lightweight aluminum panel construction for superior durability. These panels are impact, abrasion, and cut-resistant—they can even support up to 400 pounds when evenly distributed. UnderCover treats the Flex Tonneau Cover with a durable gloss-black coating for superior corrosion resistance and sleek styling.
Accessing your truck’s cargo area is simple and quick—simply drop the tailgate, pull either of the cover’s release cables, and fold the cover onto itself toward the bulkhead. You can secure the cover in the ⅔ open position with the integrated safety straps or fold it flush against the rear window, securing it with built-in prop rods for 100-percent bed access. When you’re finished loading or unloading, close the tonneau cover, fasten and lock the tailgate, and your cargo in the bed is safer than your cargo in the cab. Installing the UnderCover Flex is just as easy using UnderCover’s clamp-on mounting system.
The UnderCover Flex is just as resistant to inclement weather as it is to theft. The tonneau cover’s EPDM rubber hinges, perimeter seals, and dual-action tailgate seal prevent moisture from seeping into the bed. Any water that slips past the side seals gets diverted through built-in water channels and out of integrated drain tubes, keeping your cargo dry.
UnderCover is a RealTruck® brand. When you order this tonneau cover or any other UnderCover product from us, you’re dealing directly with the manufacturer. We back each UnderCover Flex Tonneau Cover with a limited 3-year warranty against manufacturing and material defects.
