Easy to install and remove without requiring drilling, this water-tight cover mounts flush onto your bed rails for a stylish look. FPR, or fiber reinforced plastic offers strength and low weight and the addition of LINE-X® coatings increase abrasion resistance, UV-resistance and helps to guard against water intrusion for not only a long lasting tonneau cover, but one that will look good year after year. FPR, unlike aluminum, has very good dent resistance and simply bounces back from hits that would dent an aluminum cover.

The UnderCover Armor Flex Tonneau Cover solves this problem with a unique dual action tailgate seal that allows you to open and close the tailgate with the last panel of this truck bed cover up or down. This means no more two-step tango to close your tailgate saving you time and effort. Strength, durability, great looks and function are the calling cards of the UnderCover Armor Flex Tonneau Cover. This UV-protected cover also offers a bed-rail mounting system that is equipped with rubber seals and drain tubes to keep your gear dry. Your UnderCover Armor Flex Tonneau Cover is backed by a 5-year warranty.
