OptiMat 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 OptiMat 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 to provide extra grip and prevent fuzzing and fraying. Economically priced, OptiMat has 22 ounces of felt and 16 ounces of non-washable rubber per square yard with a heat fused face. OptiMat is about ¼” thick and available in 6’ and 12’ rolls as well as pre-packaged in standard and custom sizes (For Dealers Only).
