Astroflame Intumescent Cable Tray Sleeve

The Astroflame cable tray sleeve is designed for occasions where a cable tray needs to pass through a fire partition. The opening created in the fire partition can also allow the passage of smoke and flames during a fire. When the cable tray sleeve encounters high temperatures, the intumescent material will expand to seal the hole and block the smoke and flames.
