Factory doorset manufacturers prefer the 15mm size because it allows them to use a single cutter size for both FD30 and FD60 doors, although the setup differs between applications. The brush piles in this product are black, featuring no plastic fin, which helps in reducing noise levels and resistance, making them ideal for use in various settings including areas with high humidity.
The strips have been rigorously tested to meet British Standards BS 476 Pt 20:22 for fire resistance and Pt 31.1 for cold smoke leakage. These tests have been conducted on a variety of single and double leaf doorsets, ensuring wide applicability and reliability. Furthermore, the strips are equipped with a high tack self-adhesive backing, facilitating quick and easy installation. This product is an essential component for those looking to enhance the fire and smoke resistance of their door installations in both residential and commercial settings.
