M-D 2" X 36" Pewter Aluminum Carpet Trim with Screw Nails is designed to easily cover seams or gaps between two flooring surfaces of different heights. This aluminum carpet trim effectively prevents carpet edges from fraying and stops vinyl floor seams from curling, ensuring a smooth and attractive transition between various types of flooring. It can be securely attached to wood floors using the included screw nails. For installation on concrete floors, use the screw nails along with wood pegs, which are sold separately, to ensure a stable and lasting fit. Model Number: 43858
