The 2TGF5 (14" x 12") is a rectangular dynamic fire damper.
It is installed inside HVAC ductwork to:
Prevent the spread of fire and smoke through air ducts
Automatically close when exposed to high heat
Meet fire code requirements in walls and partitions
The damper remains open during normal operation to allow airflow, but closes automatically when a fusible link melts during a fire condition.
