Roof Louvers
Louver
Surface Mount
Mounting Base
These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts. The felt seal on the face of the blades ensures quiet closing and better protection from the weather.
Mounting bases are sold separately. Louvers fit the bottom of the mounting base and must be secured to the lip of the base with sheet metal screws (not included).
Also Available: Additional louver sizes. Please select 8061T999 and specify louver dimensions.
