One piece tonneau covers are available in many different styles. Constructed from both ABS plastic and fiberglass made with black or painted to match finishes there is a style for everyone.


One-Piece Tonneau Covers


The UnderCover Classic is the original ABS tonneau: strong, weather-tight, and form fit perfectly to the bed of your truck making it the gold standard of truck bed covers. The Classic has a dual point locking system, a UV-protective, scratch resistant polymer finish, and an LED lighting system with a self-contained battery source. The textured black finish gives this ABS cover unparalleled strength at nearly half the weight of traditional fiberglass covers.

Each Classic is designed with custom fit and a double seal to keep water, and weather elements out of your bed. It’s simple to install and easy to remove, and is backed by a 3-year warranty. Turn the bed of your truck into a cargo safe with the UnderCover Classic.
