The Master Flex™ system offers all the benefits of a matting tile; it is easily installed, rearranged or replaced. What makes it revolutionary is the interlocking system that creates a durable and seamless connection that can be effortlessly installed without glue. The 591 Master Flex™ C23 matting system comes with our durable Master Trax™ carpet inserts. The 20 in x 20 in tiles cover sizeable areas easily and can be assembled on-site for installation in recessed frames in large entrances. This product is 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 drain through, keeping the surface clean and dry.
