PROMASTOP® UniCollar®
PROMASTOP® UniCollar® is an intumescent fire stopping device designed to maintain the integrity of fire-resistant floors and walls where plastic pipes or combustible services pass through.
During a fire, the collar's intumescent material expands rapidly to seal the penetration, forming an insulating, non-combustible char.
