The Master Flex™ Series are modular rubber mat tiles with an open octagonal construction with large drainage holes and a thickness of one inch. The Master Flex™ system offers all the benefits of a matting tile that is easily installed, rearranged or replaced. The tiles cover sizable areas easily and can be assembled on-site for installation in recessed frames in large entrances. Made from a durable natural rubber compound that is inherently resilient, anti-slip and withstands the heaviest foot traffic. The mat has excellent adherence and adapts to any surface while the raised studs underneath allow water to easily drain through, keeping the surface clean and dry. The mat tiles are also available with carpet inserts. The safety ramps provide a smart, sleek beveled edge to help minimize the risk of tripping. FOB Shipping Point.
