The Genesis(TM) Snap is 50% thicker than competitive covers and its heavy-duty, powder-coated bows and rails prevent water or snow build-up. The construction includes heavy-duty black powder-coated rails and bows (3 or 4 bows depending on the bed length). Pre-assembled to install in minutes. The cover installs easily onto any truck in less than 20 minutes. The cover's pre-assembled design mounts quickly to your bed with pre-marked rails and heavy-duty adjustable clamps. The aluminum black frame and Insulsnaps(TM) are designed to slide within the rail providing easy alignment and quick access to the entire truck bed.
