Babcock-Davis easy-access smoke vents are designed to open automatically when a fusible link
reaches 165 degrees F to provide emergency smoke and heat ventilation. They are spring operated with shock
absorbers to slowly open against wind or snow load. B-D smoke vents can also be equipped to open electrically.
Prompt venting in case of fire is vitally necessary to the safe evacuation of occupants and effective
fire-fighting conditions within a building. Proper venting will limit smoke and water damage to a smaller area
within a building.
