Description

This Universal Intumescent Tubular Latch Kit is a vital passive fire component designed for use with tubular latches in timber fire door applications. It is made from graphite material and has been thoroughly tested to British and European standards, including BS 476 Part 22 and BS EN 1634-1, confirming its suitability for both 30-minute and 60-minute fire doors. In the event of a fire, the graphite begins to activate at approximately $180^\circ\text{C}$ and expands up to 30 times its original volume. This expansion seals the gaps around the latch mechanism, effectively preventing the spread of fire and smoke and maintaining the integrity of the door. The material is non-toxic, non-fibrous, safe to handle without PPE, and is resistant to moisture, humidity, and atmospheric pollution.
