UltiMat performs as well on wall-to-wall carpet as it does on hard surfaces. Place the reverse waffle "tentacle grip" side face down on hard floors and you have more gripping power than any other pad. Turn UltiMat over - rubber side up - and you have a pad that keeps area rugs securely in place over wall- to-wall carpeting. The surface is specially treated with latex to provide extra grip and more firmness than OptiMat. UltiMat is ¼” thick and made with 28 ounces of fiber and 20 ounces of washable rubber and 5 ounces of latex face coat per square yard. UltiMat is available in 6’ and 12’ rolls as well as pre-packaged in standard and custom sizes (For Dealers Only).
