RetraxONE MX combines everyday convenience with automotive-grade durability. Its sealed-bearing track system delivers jam-free, maintenance-free motion every time you open or close your GM standard-bed truck, while the Wide-Rail kit provides a seamless look and extra sealing over the stake pockets.
Molded from a single sheet of polycarbonate and finished in a textured matte-black coat, the cover shrugs off dents, scratches, UV fade, and temperature extremes. Internal aluminum reinforcement rods add rigidity without excess weight, and automotive-grade weather seals keep rain, snow, and dust outside where they belong.
