Durable, washable all-rubber mats stop dirt in its tracks! The SuperScrape traps tough dirt and grime outside the door, before it enters the building. The specialized molded rubber tread pattern is slip resistant and provides anti-fatigue properties. Constructed of extra heavy rubber, the SuperScrape stays in place. Available in either a 100% Nitrile Rubber version (oil and grease resistant) or a Natural Rubber version.
