The RetraxONE XR retractable truck bed cover is manufactured from rigid, powder-coated polycarbonate material which provides exceptional performance and phenomenal security. This cover features our Trax Rail system that is compatible with most T-Slot accessories. Pair your cover with add-ons from Rhino, Thule and Yakima to optimize cargo capacity. The durable construction provides superior impact resistance and UV protection against any climate. The low-profile, matte finish provides a polished look but also delivers incredible scratch resistance against your toughest jobs. Unlike other covers, this cover is made from one piece of material engineered to retract without joints or hinges that might trap dust, wear out or freeze hindering its mobility. Our patented design and rail seal streamlines the overall appearance and provides dependable, weather-tight protection from the elements. The compact storage container features a unique spiral track system that prevents this hard-cover from scratching or damaging itself from daily use. The cover has a sealed ball-bearing roller system that glides effortlessly along the rail with no need for pull straps, snaps, or springs. Additionally, this cover is key lockable in any position giving you flexibility and security for your storage needs. The RetraxONE XR is backed by a 1-year warranty.
