Which material is commonly used for tack strips (grippers)?

Tack strips, commonly used as grippers in carpet installation, are typically made of wood. This material is favored because of its balance of strength, flexibility, and ease of fastening. Wooden tack strips provide a sturdy support system for the carpet while allowing the pins that hold the carpet in place to penetrate the material effectively. The wood absorbs some of the pressure and stress exerted on the carpet as it is walked on, helping to maintain the integrity of the installation over time.

While other materials like plastic, metal, and rubber may be utilized in various flooring applications, they do not offer the same properties that make wood an ideal choice for tack strips. For example, plastic may not provide sufficient grip, and metal could potentially be too rigid or sharp, leading to safety concerns. Rubber, while offering some cushioning, generally lacks the ability to secure the carpet in place as effectively as wood tack strips can.
