The Access Roll-Up Bed Covers are designed to custom fit for just about every truck bed in the marketplace, guaranteeing great style and tight seal. The covers are all compatible with bed rails, bed caps and tailgate protectors, with drop-in, under-the-rail and spray-on bed liners, and they are quickly installed with a clamp-on design. The Access Bed Covers can also be combined with the Adarac Bed Rack System. The covers have secure locking mechanisms. Add a tailgate lock, and the load is not only protected against the elements, but also against thieves. The Access Covers stow neatly behind the cab when not in use, always in place to cover a load when needed. Covering and un-covering the bed is a quick and easy one-man operation. With the cover in place, air turbulence is reduced behind the cab, reducing air drag and improving fuel economy. The Access Covers are always there when needed. They are stylish and make trucks into true all-purpose vehicles, meeting whatever needs the owners have
