Ideal for medium/heavy-duty wet industrial conditions, these resilient, anti-fatigue mats feature an anti-slip surface texture and multi-nib backing to promote sure footing and a large circular hole design to facilitate easy drainage. Chemical-resistant rubber compound greatly reduces fatigue and provides support to the worker. Also available in a solid design (Cushion-Ease #556). Specify size and color for either style: Black (BL) - grease-resistant and features a 1-year warranty. Red (RD) - grease-proof and features a 5-year warranty. Both models can be locked together on site with the M.D. Ramp System™ (pictured with #550), which works just like a picture frame, allowing you to configure male and female ramps to create custom flooring for your workstation. Simple, multi-dimensional ramp system features molded-in nitrile rubber for grease resistance and uses very few parts, reducing the risk of the mat becoming a tripping hazard. Also available in custom sizes. Please call for more information.NOTE TO CUSTOMER: CONNECTOR IS ONLY AVAILABLE IN BLACK.
