Ceiling Truss Shutter - White enamel finish

The Model CTRF is a CEILING TRUSS flanged frame horizontal mount automatic exhaust shutter. It is designed to allow airflow in one direction and to prevent reverse airflow. The blades open with airflow and close by gravity when the fan shuts down. Ideal for use with whole house fans without cutting the trusses away. The shutter comes standard with a Polar White Enamel Finish and is flush mounted for a clean appearance.
