The RetraxONE MX is a retractable tonneau cover for the 2014-2019 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 with the 6'6" bed and standard rails. It is made for drivers who want a low, flush cover that opens with one hand and keeps the bed looking factory. Push the latch button and the handle springs up, and the cover locks in any position, so tall cargo can ride in the open section. The top is a single aluminum-reinforced polycarbonate panel with no slats or hinges, and CoreTrax bearings in a spiral-track canister keep it rolling smoothly.
