The RetraxONE MX is a premium manual retractable tonneau cover designed for dependable protection, smooth operation, and long-term durability. Featuring a one-piece aluminum-reinforced polycarbonate construction, the MX eliminates hinges, joints, and other leak-prone wear points—providing the unmatched performance that's trusted by over a million truck owners. Engineered to perform in demanding environments, the RetraxONE MX offers exceptional impact resistance and UV protection—proven in extreme temperatures ranging from -50 to 200ºF. An advanced water management system seals tightly and directs excess moisture out of the bed through integrated drain tubes, safeguarding your cargo. Everyday utility is unmatched with the RetraxONE MX—with a simple lift of the latch and press of a button, the spring-loaded handle deploys for quick, one-handed operation. Inside the rails, exclusive CoreTrax™ technology delivers reliable, maintenance-free performance with precision ball bearings and a custom track system that resists sticking, freezing, and wear. Security and flexibility are two hallmarks of the RetraxONE MX. The cover can be locked in any position along the rails, allowing you to accommodate oversized items while keeping a portion of the bed shielded against water, dirt, and prying eyes. A streamlined, low-profile design sits flush with the bed rails for a subtle appearance that won't obstruct rear visibility. The textured matte black finish adds durability without distracting from your truck's factory appearance. At the front of the bed, a compact canister with a spiral track system ensures smooth retraction while minimizing friction, scuffs, and long-term wear. Installation is quick and easy thanks to the integrated clamp-on mounting system, requiring no drilling or permanent modifications. Most installations take under an hour using basic tools. Each RetraxONE MX is proudly engineered and assembled in the USA and is backed by a 1-year warranty.
