The Retrax RetraxONE XR is a low-profile retractable cover made from one-piece polycarbonate with a scratch-resistant matte finish and integrated Trax Rail System for rooftop accessory mounting. It preserves cargo capacity above and below the cover, opens and closes easily one-handed with sealed ball-bearing rollers, and works with most T-slot accessories to expand hauling options for Ford F-150 Super Crew and Super Cab 5.5' beds (2004–2008) without stake pockets.
