The RetraxONE MX combines strong and durable single-piece polycarbonate material with a stylish, scratch-resistant matte black finish. Like Retrax’s other retractable covers, the MX enjoys a low-profile design thanks to a front canister that fits flush with the truck bed cover, streamlining the overall appearance. The RetraxONE MX easily glides on sealed ball bearings, making it the most easy-to-use retractable bed cover on the market. There’s only one…RetraxONE.
