Perfect for indoor and outdoor entranceways, the WaterGuard keeps your office or home clean, dry and safe. Carpet covered, rubber reinforced nibs scrape debris and pull moisture away from shoes. Dirt and water are trapped by rubber reinforced polypropylene carpet ridges. Recommended as an indoor mat, but substitutes as an outdoor mat in warm to moderate climates. 100% rubber backing for maximum durability. Easy to clean and maintain—just shake out, vacuum, hose and dry or clean with a light carpet cleaning machine. Not recommended for use in areas exposed to grease or petroleum products. Ideal for use in indoor and outdoor entranceways, ice machines, vending areas, kitchens, breakrooms, high traffic doorways, and production areas.
