Frost King's "EZ" Self-Stick Aluminum Carpet Bar is designed to join carpet with vinyl, tile, wood, or other flooring of a lower height. Carpet bars prevent carpet edges from fraying, vinyl floor seams from curling and create a smooth transition between different flooring surfaces. Plus, it's "EZ" to install...just peel off the protective paper, press into place, and you're done! No fasteners required. They are the perfect finish to your flooring project.
