*Remove the sand paper the comes on the ramp, add strips of “heavy duty” VELCRO to the length of both base pieces, then take a foam back mat (not too thick) and cut it to width of both pieces of ramp platform. Then attach the two pieces of mat to ramp base. *Note: the best type of mat to buy is one that has “loops” or called “Berber”.
