Roof Louvers
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).
Motor kits (sold separately) let you open louvers when you’re not running your exhaust fan but still want to let air flow into your ventilation system.
Also Available: Additional louver sizes. Please select 8061T999 and specify louver dimensions.
