The Dee Zee Rubber Truck Bed Mat is an affordable and easy-to-install accessory that protects your bed from dents, dings, and scratches caused by shifting cargo. The mat is made of heavy-duty, 3/8-inch thick rubber, which is resistant to extreme weather, UV rays, and damage from chemicals like oil and gas. To install the mat, simply unroll it and lay it down in your truck bed. Rubber cleats on the underside of the mat hold it in place. The cleats also allow water to drain under the mat and out of your bed, so you won't have to worry about rain water accumulating underneath. Dee Zee stands behind their Rubber Truck Bed Mat with a three-year warranty.
