PROMASTOP® UniCollar® is a fire stopping device with intumescent material, designed to maintain the integrity of fire-resistant elements penetrated by various plastic pipes. It is suitable for retrofit installation in floors and walls similar to those in which it has been tested. In the event of a fire, the intumescent material rapidly expands to close off the plastic pipe or combustible insulation, forming an effective insulating barrier.

Each PROMASTOP® UniCollar® is supplied in an individual box containing a 2250 mm length (150 segments) along with fixing accessories.
