Ultra-clear mat with a standard lip is designed to preserve and protect the beauty of laminate, wood, tile and other hard flooring. Anti-skid texture on the underside reduces mat movement and keeps mat securely in place. Engineered for optimum clarity, high performance and a smooth effortless roll, thick vinyl mat with a straight edge is designed for heavier use to protect against wear and tear from chair casters. Mat offers an intermediate thickness of 110 mil. Lip measures 25" x 12".
