      Description

      Protects and Secures Cargo. As a hard folding cover, the UnderCover Armor Flex Tri-Fold Tonneau Cover automatically latches to the rail system of your GMC Sierra 1500’s truck bed for ultimate securement and protection from the elements. It looks great doing it with its low-profile design for smooth aesthetic integration. The cover comes with a dual-action tailgate seal to enable universal tailgate operation, allowing you to close the tailgate with the last panel of the cover up or down.

      Convenient Tri-Fold Design. Due to its design, this tonneau cover provides 3 secure riding positions. You can drive with the cover closed or open without having to take the entire thing off.

      Durable Construction. The Armor Flex tonneau cover is notable for its matte-black LINE-X specialty automotive coating, which provides advanced protection from dents and scuffs. This is in addition to ultra-strong panels that comprise the cover to ensure long-term use.

      Easy to Install. This tonneau cover is very easy to install. Expect to do so within 15 minutes.

      Five-Year Manufacturer’s Warranty. UnderCover, Inc. warrants that this tonneau cover will be structurally free from defects in material and workmanship for 5 years from the retail date of your purchase. Some exclusions may apply; please see manufacturer’s warranty for details.

      Application. The UnderCover Armor Flex Tri-Fold Tonneau Cover is designed to fit the 2019-2022 GMC Sierra 1500 with the Standard Box and MultiPro Tailgate.
