What are the two major purposes of tack strip?

The two major purposes of tack strip are to hold stretched carpet and to protect the carpet edge. Tack strips are typically installed around the perimeter of a room, providing a means to anchor the carpet in place. When carpet is stretched over the tack strip, the sharp tacks grip the back of the carpet, ensuring that it stays securely in position. This anchoring prevents the carpet from shifting, which could lead to wrinkles or uneven surfaces.

Additionally, the tack strip helps protect the edge of the carpet. By providing a dedicated area where the carpet can be fastened, it reduces the risk of fraying or damage to the carpet edges, especially in high-traffic areas. This not only helps maintain the integrity and appearance of the carpet over time but also contributes to the overall durability of the flooring installation.

Other options do not encapsulate the primary functions of tack strip as effectively. While support for padding or aesthetic enhancement may be relevant in broader carpet installation practices, they do not align with the fundamental role of the tack strip itself.
