UnderCover is the manufacturer of a revolutionary ABS one-piece truck bed cover. The company was founded in 1999 and entered the truck bed cover market in 2001 with the “UnderCover Classic.” This was the first truly competitive alternative to the traditional fiberglass truck bed cover. The bed cover's patented design and a proprietary blend of plastic and polymers give this cover unparalleled strength and durability. Most UnderCover products are approximately half the weight of traditional one-piece covers, making them easy to remove while retaining structural strength.
