The LINE-X Deluxe Roll-Up Tonneau Covers look great and can be installed in just minutes. The low-profile design improves the look of your truck while the quick-release system allows you to completely remove the cover without tools and automatic tension adjustors eliminate the need for periodic manual adjustments. To protect your cargo, simply roll the cover closed and securely latch it. When you need full use of the truck bed, roll the cover open and secure with the retainer straps.
