Keep your floors and carpets clean without breaking your budget by placing Andersen’s Waterhog Classic Entrance Mat in your office's lobby. The rubber-reinforced nubs hold their shape and won’t flatten as you wipe your shoes. A water dam on the border of the mat keeps water and dirt from spilling onto your floors. The anti-static mats are safe to use in computer rooms and around electronic equipment. Choose from 10 great colors and two backing types. Your mat won’t fade or rot because the fabric is made of 100% polypropylene. To clean, just vacuum or hose off and hang to dry. Listed size is approximate.
