This is a premium mat made from an EPDM/SBR non-staining, non-marking rubber compound. Excellent for use in high-traffic areas, it can be placed on floors without the fear of ruining existing floor finish. Extra-heavy, vulcanized-rib construction increases traction and withstands abuse from equipment. The Rib Mat resists a number of chemicals and fluids, while maintaining the integrity of the mat. Elevated ribs provide continuous airflow beneath the mat. Fluids and debris can be easily swept away.
