The Genesis Tonneau Cover was designed to be effective and lightweight with its vinyl material. The cover uses an extremely low-profile design that sits low on your Ranger's bed. It can be fully opened for 100% bed access and can also be left open while driving due to an integrated clip/strap system. The product comes fully assembled and comes with all mounting hardware, including adjustable clamps. No drilling or special hardware is required. This tonneau cover is not lockable.
