Roll-X tonneau covers combine all the great features of a roll up cover plus the security of a hard folding cover like the BAKFlip. The cover is an aluminum track similar to a garage door with a leather grain vinyl coating on the top. Much like a garage door it includes a track system that clamps to the bed rails for the cover to roll in and out on. When opened the cover can be stowed in the open position using built in straps which allow the truck to be driven with the cover in the open position. Just like the BAKFlip the tailgate has to be opened to unlock the cover so if the tailgate is locked the entire bed is secure.
