Please Note: For safety, it is always best to secure the stair treads in place. The backing of our stair treads was designed to provide the best results with rug anchoring solutions without damaging your staircase. For a slip-free installation, we recommend you apply 2 thin strips of double-sided carpet tape included in your purchase. Our double sided-tape is engineered to ensure that no sticky residue is left on your staircase.
