What is a suitable alternative for architectural tack strip (gripper)?

The correct answer is double-stripping, which serves as a suitable alternative for architectural tack strip or gripper in certain flooring applications. Double-stripping involves the use of two layers of strips that can effectively grip and hold carpets in place. This method can provide a strong anchor for the carpet, ensuring stability and reducing movement over time, much like traditional tack strips.

The concept of double-stripping mimics the gripping functionality of architectural tack strips but may be employed in situations where the standard tack strip may not be ideal due to various reasons such as uneven subfloor conditions or specific installation requirements. Moreover, using double strips can be an effective solution when installers want to enhance the overall grasp that the material has on the flooring.

Other choices, while they might be used in flooring applications, do not provide the specific advantages of grip and stability that double-stripping offers. Nailed strips are less versatile and may not provide the same level of performance as double-stripping in terms of secure attachment and flexibility. Wooden beam support and metal frame options are not typically used for securing carpets, as they serve different structural roles and do not directly engage with carpet installation in the same manner as a tack strip or double-stripping would.
