Click Image for Gallery
Backdraft dampers prevent the unwanted flow of air into a house through exhaust ducts when the exhaust fan is off. These sensitive spring-loaded backdraft dampers will accomplish this with minimal effect on the exhaust stream, while providing a good seal against backdrafts. Each is 3 inches long.
