MG2-A U - Surface-mounted collar

The MG2-A U surface-mounted fire resistant collar is suitable for ventilated and non-ventilated plastic pipes (PVC, HDPE, PP, ABS). It prevents the propagation of fire up to 120 minutes in rigid walls and floors and in flexible walls. In case of a wall, a collar is installed on both sides of the wall. In case of a floor, a single MG2-A U is enough on the lower side of the floor.
