The operation of this cover allows it to always stay flush to the rails, which helps to create a dependable seal and keep the elements out and protect your cargo. The RetraxONE MX has a sealed ball-bearing roller system that glides effortlessly along the rail with a convenient handle that eliminates the need for pull straps, Velcro, snaps or springs. The RetraxONE MX is key lockable at any position giving you unlimited flexibility in your hauling capacity. The sealed ball-bearing rollers are mounted onto the support beams allowing the RetraxONE MX truck bed cover to retract or close effortlessly without the use of springs or any kind of mechanism - no moving parts to jam, freeze or fail.
