The Genesis Elite Tonneau Cover was designed to be effective and almost maintenance free. No specialized cleaners are needed; just rinse with some water and let it air dry. This is due to the HAARTZ Twill fabric's design. 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.
