Floor mat protects your floors in high-traffic areas for indoor and outdoor use. Bi-level construction keeps dirt and moisture trapped beneath the shoe level. Raised border keeps water and dirt in the mat and off the floor. The carpet-covered, rubber nibs scrape shoes of debris and pull moisture away from shoes. Premium, 24 oz. polypropylene carpet dries quickly and will not rot. Mat offers 100 percent rubber backing for maximum durability. Rubber borders strengthen and enhance safety. Waterguard floor mat passes flammability standards DOCFFI-70.
