The RetraxPRO MX retractable truck bed cover is part of our Premium Aluminum Series covers. The Premium Aluminum Series covers are constructed from industrial strength aluminum slats that provide unsurpassed strength and ruggedness. The RetraxPRO MX combines industrial strength aluminum construction with an incredibly resilient matte finish. The matte finish on the RetraxPRO MX provides incredible scratch resistance and adds style to your truck.

The RetraxPRO MX not only provides rugged protection for your truck bed it also provides a patented low-profile design that enhances the appearance of your truck. The compact storage container features a unique spiral track system that prevents the cover from coming into contact with itself as it opens and closes. The operation of this cover allows it to always stay flush to the rails and creates a dependable seal to help keep the elements out and protect your cargo.

The RetraxPRO 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 RetraxPRO MX is key lockable in any position that gives you unlimited flexibility in your hauling capacity.

Overall, the product really functions very well and allows me to have my other rack setup over the bed without having to go the topper route.
