Terms of the Trade: What Is a Tack Strip?

A tack strip.

A tack strip is a crucial element of carpet installation. A long piece of wood with many tacks or sharp nails studded in it, the tack strip is what keeps the carpet grounded to the floor. The strip itself is nailed to the floor around the perimeter of the room, and the carpet is then stretched and anchored to the nails on the strip. The polished look of many carpet installations is when the carpet is wedged between the wall and the edge of the tack strip, creating a rounded appearance that's also secure.
