Legrand's FlameStopper Thru-Wall/Floor Fittings
Legrand’s FlameStopper Thru-Wall/Floor Fittings are ready-to-use options for transitioning cables through firewalls and floors in new and retrofit applications. They are designed for rapid expansion when exposed to fire or high temperatures to quickly seal the pathway and prevent the passage of flames and smoke. The mechanical doors provide steel barrier between rooms, and fittings may be pre-installed as they maintain fire ratings while doors remain closed until cables are installed. They are plenum-rated and can be used with any wall thickness.
