Acme All Aluminum 24 Inch Shutter

ACME aluminum wall shutters have a corrosion-resistant heavy gauge aluminum frame.

These shutters feature precision counterbalanced aluminum blades that open easier and wider to permit higher fan capacity. Nylon bearings throughout are corrosion proof to prevent sticking.

Exhaust fan louver shutters open automatically when exhaust fan is on and close automatically when the fan is off.
