Product Information
Fire doors are designed to operate to prevent the spread of fire and smoke. The most common type of fire door is the fire shutter, which closes to prevent the spread of smoke and fire. One way a fire shutter can close is Gravity Close with the shutter in the open position the drive shaft must release enabling the shutter to close in a controlled manner. Marantec UK offer the NBG range of fire door operators for gravity close applications.
