My tailgate mat is attached to the gate... There are two ways, either 3M double sided tape, not provided, or tapping holes and screwing it in with the provided screws... I chose the screws... The brand is ProTeca from
www.pickupspecialties.com... Their price is $29.95 less shipping... I used black electricians tape just to cover up any red from the truck showing around the edges... It has gone through severe winter conditions in the Oregon Cascades without any problems... It's a must if you have a bed mat...
