Dura Trax® Grande is a full ONE-INCH thick high performance anti-fatigue floor mat representing the ultimate in comfort and durability for todays industrial environments. A nitrile rubber top surface provides a noticeably softer and more comfortable work surface and a diamond-plate design offers greater slip resistance and is easy to sweep or mop clean. Dura Trax® Grande combines the heavy-duty nitrile rubber top surface with a dense sponge backing utilizing Notrax® exclusive UniFusion technology. This virtually eliminates the possibility of de-lamination. All Notrax® laminate floor mats come standard with RedStop, a uniquely engineered non-slip backing technology that eliminates the slipping and sliding of floor mats on smooth surface flooring such as vinyl composite tile, painted or epoxy coated concrete, vinyl sheet flooring, carpet, and ceramic tile.
