The RetraxPRO MX retractable truck bed cover is made with industrial strength aluminum slats for maximum durability against the elements. The PRO MX can support up to 500 lbs. of evenly distributed weight. The PRO MX powder-coated matte finish provides superior scratch and UV protection. This retractable cover is so durable that we back it for life with our Legendary Lifetime Guarantee. This retractable truck bed cover features a stylish matte finish and a low-profile, patented design that streamlines the overall appearance and provides a tight seal. Its cannister lies flush with the cover and is completely hidden inside the bed of the truck while maintaining some clearance from the truck bed so that you can transport long pieces of cargo like wood pallets and other items. Furthermore, the PRO MX’s compact storage container features a unique spiral track system to prevent the cover from being in contact with itself as it opens and retracts, protecting the finish of the cover from scratches resulting from daily use. The RetraxPRO MX also has a sealed ball-bearing roller system that glides effortlessly along the rail with a convenient handle that eliminates the need for pull straps, snaps, or springs. The RetraxPRO MX is key lockable in any position giving you unlimited flexibility and security for your cargo storage needs. The RetraxPRO MX is made in North Dakota and backed by our US-based customer support team.
