RetraxPRO truck bed covers are made with industrial strength aluminum, giving them the strength to support distributed loads of more than 500 pounds! The RetraxPRO features a limited lifetime warranty, meaning you'll never have to worry about your bed cover once you have it installed. Retrax retractable truck bed covers feature Sealed-For-Life Bearings mounted onto each section of aluminum for continuous, smooth, one-handed operation allowing the retractable cover to open and close easily without the need for pull straps, snaps or springs. Our exclusive use of ball-bearings also prevents the cover from binding when opening or closing. Our patented low-profile design is always flush, enhancing the integrity of your truck's style rather than overcoming it. Your cover will seal tight and look good. Unlike soft covers that bulk up when rolled, the flush front cover streamlines the overall appearance and provides a firm, dependable seal that keeps out the elements and helps keep the bed dry.
