Fire-Rated Airflow Dampers
In the event of a fire, these dampers automatically stop airflow through duct. They have a fusible link that melts at 165° F, releasing a spring and causing the blades to close. Dampers meet UL 555 fire safety standards to help prevent the spread of fire for 1 ½ hours. They are undersized to fit inside duct.
