Abstract: A device for use in securing a liner in the bed of a truck having side walls with an inwardly extending upper flange and a lip extending downwardly therefrom. The device has a back portion with a clamp disposed near the upper edge thereof for engaging and gripping the lip, and a base portion extending outwardly from the back portion for engaging the truck wall and stabilizing the device. A screw is inserted through the liner and into the back portion of the device, thereby holding the liner in place while allowing relative expansion and/or contraction between the liner and the bed from temperature changes without causing distortion of or damage to the liner.
