Aluminum Smoke Vents
Babcock-Davis galvanized steel smoke vents are manufactured to automatically open when a fusible link reaches a certain temperature, allowing heat and smoke to escape during a fire. They are spring operated with shock absorbers to slowly open against wind or snow load. Smoke vents can also be equipped to open electrically.
