UnderCover Ultra Flex Tonneau Cover
The UnderCover Ultra Flex is a premium, hard-folding tonneau cover designed for a sleek, low-profile appearance and durable protection for your truck bed. Built with rigid yet lightweight materials, it combines secure cargo protection, weather resistance, and easy operation.
- Premium hard-folding design with a flush, low-profile look.
- Aluminum-skinned top panels and L-rails with a matte-black smooth finish for durability and style.
- 400 lb. evenly distributed weight capacity thanks to rigid yet lightweight aluminum construction.
- Carpeted under panels to protect cargo and reduce noise.
- Automatic slam latches for quick, secure panel engagement.
- EPDM rubber hinges, perimeter seals, and dual-action tailgate seal to keep out water and the elements.
- Integrated drain channels and tubes for effective water management.
- Integrated prop rods support the cover upright for full bed access when needed.
- Simple clamp-on L-rail system for a no-drill installation approach.
- 5-year warranty for long-term assurance.
The Ultra Flex operates smoothly: drop the tailgate, release the rear latches, and fold the cover forward. Use the safety straps to secure it in the 2/3 open position or fold completely and support it with the built-in prop rods for full access. Closing engages the slam latches and seals the cover tightly against the perimeter and tailgate seals.
*Installation/Compatibility note: Simple no-drill installation using the clamp-on L-rail system; verify fit for your specific truck year, make, and model before purchase.
