RetraxPRO MX bed covers are made with heavy-duty aluminum slats covered in a matte powder coat, giving them the strength to support distributed loads of more than 500 pounds! The RetraxPRO MX features a limited lifetime warranty, meaning you'll never have to worry about your bed cover once you have it installed. Sealed ball-bearing rollers are mounted onto each section. This allows the retractable cover to open and close easily with one hand, without the need for pull straps, Velcro, snaps or springs. Ball-bearings provide smooth operation, preventing 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. The RetraxPRO MX cover can be latched or key locked in any position. This allows for unlimited flexibility in hauling almost any object, and the secure Dual Latch Locking System provides protection unlike any other cover.\nRetraxPRO MX Retractable Tonneau Cover; Rugged - Aluminum Construction; Matte Black; GM 5.8' Bed 1500 (2019)\nBefore purchase please verify if you have New Body Style or Legacy (Chevy)/Limited (GMC) on 2019 Silverado/Sierra 1500 - This part is for the New Body StyleNOTE: This will fit models with or without Multi-Pro Tailgate\n2019 Chevrolet Silverado 1500 69.9 Bed, 2019 GMC Sierra 1500 69.9 Bed
