Description

The Astroflame range of Astro FT Fire Trunking Sleeves are intended for use where plastic trunking passes through a fire rated wall. The sleeve reinstates the fire rating of the wall which would otherwise be lost.

In the event of a fire, the Astro FT Trunk Sleeve expands with the heat, crushing the trunking and closing off the hole to the fire for at least 2 hours.

The FT Trunk Sleeves are available to fit common sizes of plastic trunking and are suitable for retro fitting with access only required from one side. They are suitable for use with plastic trunking or can be used with cabling passed directly through the sleeve. 25mm thick wall
