Duncan Metal Grille

Get full control of your airflow with a combination of an adjustable and directional louver.

Adjust the volume of air, then direct it where you want it to go. Ideal for tricky layouts where air needs to be pushed away from walls or spread across multiple directions.

An adjustable louver lets you open or close the vent to control how much air flows into a room.

Perfect for reducing airflow or shutting it off entirely in spaces that don’t need it.

A directional louver pushes air in one or more directions to improve circulation. Choose from four different airflow directions to guide air away from walls or ceilings and into the areas where it’s needed most.

Choose a grille without a louver for vertical, unrestricted airflow. This option allows air to flow freely with no ability to adjust volume or direction. This option is ideal for return vents and passive openings.



Note: Be sure to select the right grille with mounting holes, screws, or edge style for your installation needs (floor, ceiling, or wall).
