FULL BED ACCESS
When you need to haul large items, just fold the cover toward your cab and secure it in place with the supplied prop rods. The prop rods rest in an improved rail clip when not in use and upgraded cab bumpers prevent the cover from scuffing your paint.

UPGRADED SIDE RAILS
Channeled rails hold the cover in place while shut. These rails feature rubberized endcaps, which prevent any raw aluminum from being exposed.
