B312 Jumbo Fire Collars
Fire Collars for the prevention of fire where large PVC and PE plumbing pipes penetrate fire barrier floors and walls.
The collars' low profile and quick-clip construction allows fast, simple installation either before or after pipework has been erected.
Jumbo Fire Collars have an outer casing of powder coated steel with a liner of intumescent material.
Simple to install as no crushing spring is required.
