Cable Tray Pillow

A reinforced, glass cloth intumescent cable tray pillow, filled with a fireproof sponge as well as intumescent. Expands to 3 times its original size when exposed to fire, filling gaps in or around cable trays in fire-rated walls, floors or ceilings.

The pillow expands at low pressure, locking together to seal off fires, whilst preserving the integrity of the cable tray.  In the event of a fire, the intumescent breaks through the pillow and expands to seal the cable tray.

Designed with a retention tag to secure onto cable trays, easily removed during wiring inspection and maintenance. Electricians can simply place pillows into cable tray systems to protect cables and replace them where necessary.

Passive fire products manufactured with intumescent assist in compartmentalising fires, preventing fires from spreading within a building. This allows occupants to safely evacuate a building via an escape route.

  • Pillows provide up to 4 hours of fire protection.
  • Available in a range of sizes to fit into varying cable trays.

Our electrical and plumbing products meet IET wiring regulations as well as Document B & E of Building Regulations tested to European and British Standards. Browse our full range of electrical and plumbing products.
