The 2-1/2″ x 36″ Unfinished Hardwood Seam Binder easily covers a seam or gap between two flooring surfaces of equal height. Seam Binders prevent carpet edges from fraying, vinyl floor seams from curling and creates a smooth transition between different flooring surfaces. Seam Binders are easily secured to wood and concrete floors with provided Screw Nails. For installation on concrete floors use Wooden Pegs (sold separately).
