The tonneau cover clamp is typically made of Aluminum and rigid plastics, to ensure it is strong enough to withstand the forces of travel and the weight of the tonneau cover. It may also have a rubberized coating to protect the finish of the truck's bed and to prevent scratching or other damage. The tonneau cover clamp is designed with a thumbscrew, which allows the user to easily open and close the clamp without the need for tools.
