Rubber-Cal''s Coin-Grip rubber stair mats are the ideal safety solution for stairways in residential, commercial, and industrial settings. These durable mats are made of a mixture of natural and reclaimed rubbers, making for very durable products that can endure repetitive physical abrasions from foot traffic, as well as harsh weather conditions such as the sun''s UV rays, environmental ozone, and moisture from rainfall. Each pack has six individual step mats that have a 1-inch nose designed to firmly grip onto their individual steps. The defining feature of these non-skid step mats is their coin-patterned surface texture. The coins are circular protrusions that are slightly raised and they are laid out in a pattern that is designed to increase grip and traction for your feet as you go up and down stairways. Rubber already has a natural ability to increase traction. This ability is enhanced by the surface texture present on the step pads. These rubber stair mats are recommend for use on indoor or outdoor steps. Installation is easy with the use of a double-sided tape or the step tread mats can be loose-laid in residential applications.
