The Waves Rubber Stair Treads help you maximize staircase safety by converting your stairs into non-slip steps. The wave-patterned staircase mats are each 9.75 in. x 29.125 in. in size. Thus, these rubber step mats fit easily over most residential and commercial stairs, affording them a layer of protection, slip-resistance, and style that they would not have otherwise. The stair-tread material reclaimed and natural rubber is also highly resistant to weathering from UV-rays, ozone, oxygen, and moisture. This makes them well-suited as non-slip, outdoor stair treads. Furthermore, these slip-resistant treads also help prevent your stairs themselves from incurring physical damage. After all, they are made of highly durable natural and reclaimed rubber materials. These wave-patterned staircase mats are made of 3/16 in. thick rubber, which makes them extremely well-suited for withstanding constant use for extended periods of time. In addition, these slip resistant treads feature wavy corrugations that complement rubber’s natural, traction-enhancing properties. Such a surface texture increases the number of points of contact between people’s feet and the stairs, significantly enhancing their grip as they walk. Finally, the Waves Rubber Stair Treads are very DIY-friendly easy to install with common adhesives. You may use a double-sided tape adhesive for a semi-permanent installation, which allows for easy removal for replacement or relocation. Color: Black.
