Features a multi-directional molded tread pattern that effectively scrapes tough dirt and grime from shoes. The unique drainable borders help filter water off the mat, making it ideal for use outside as a scraper mat or as a slip-resistant mat in wet areas. Certified high-traction by the National Floor Safety Institute (NFSI). Grease/oil and chemical resistant. Lightweight flexible design ensures easy handling and cleaning (shake off soil and hose off), can be commercially laundered or autoclave sterilized.
