The Retrax RetraxONE XR is a matte, one-piece polycarbonate retractable cover that pairs a low-profile sealed design with an integrated Trax Rail System for accessory mounting. It opens and closes easily one-handed using sealed ball-bearing rollers, supports cargo above and below the cover, and resists scratches while sealing the bed for Ford Super Duty F-250/350 short beds (1999–2007) without stake pockets.
