The Unfinished 2-Inch x 36-Inch Hardwood Carpet Trim easily covers a seam or gap between two flooring surfaces of unequal height. Hardwood Carpet Trim prevents carpet edges from fraying, vinyl floor seams from curling and creates a smooth transition between different flooring surfaces. Hardwood trim is easily secured to wood and concrete floors with provided screws. For installation on concrete floors use Wooden Pegs (sold separately).
