The impact mat fits trucks that have an existing spray-in liner or no bed liner. An integrated tailgate gap guard hinge connects the bed to the tailgate for easy cargo loading. The polypropylene top layer offers a flat work surface that is slip and skid resistant. A 3/4" padded layer provides dent and impact resistance while offering a cushion for your knees. This mat is quick and easy to set up, allowing you to use quickly on the jobsite.
