This high-end, hard-folding tonneau cover is manufactured from only the best materials, including powder-coated aluminum top panels and L-Rails. The rigid aluminum construction can withstand up to 400 pounds of evenly distributed weight. It's also highly durable and theft-proof; with the tailgate locked, your cargo in the bed is safer than if it were in the cab! The UnderCover Ultra Flex Tonneau Cover isn't just theft-resistant but also highly weather-resistant! UnderCover utilizes a sleek, low-profile design with automatic slam latches, holding the cover taught against the integrated EPDM rubber perimeter seals. As a result, water and dirt don't stand a chance! This cover also features a dual-action tailgate seal, allowing you to operate the tailgate with the cover opened or closed! Operating the UnderCover Ultra Flex Tonneau Cover is quick and simple. To release the cover, drop the tailgate, pull the latches near the rear of the bed, and fold it toward the bulkhead! You can either secure the cover in the 2/3 open position using the nylon straps or fold it flat against the rear window and support it upright with the integrated prop rods! Closing the cover is just as easy; simply fold it back toward the tailgate as the cover's innovative slam latches automatically engage, locking each panel into the L-Rails. UnderCover backs the Ultra Flex Tonneau Cover with the security of a 5-year warranty, covering any manufacturing or workmanship defects.
