Description
Keeps Cargo Secure and Protected. With the UnderCover Ultra Flex Tri-Fold Tonneau Cover - Black Textured, you will never have to worry about the cargo in your GMC Sierra 1500 being without proper concealment or securement in the truck bed. That’s not all; the Ultra Flex is popular for its several features. You will get a dual-action tailgate seal for closing the tailgate with the cover up or down. The cover will also look great on your truck: with an ultra low-profile design and carpeted underpanels to integrate into the truck’s factory look.
Tri-Fold Design. With its 3 secure riding positions, the Ultra Flex enables you to drive with it closed or open without having to remove it from the truck bed.
Durable Construction. The Ultra Flex tonneau cover is made to withstand the worst weather and driving conditions. It is finished with a black textured color to prevent fading.
Easy Installation. This tonneau cover is an easy clamp-on application, with newly designed L-rails. You can finish the job 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 Ultra Flex Tri-Fold Tonneau Cover - Black Textured is designed to fit the 2019-2024 GMC Sierra 1500 with the Short or Standard Box.
