The EZ-Flo Wall/Ceiling Register is designed for wall or ceiling openings to control airflow for increased comfort. This register ensures quiet airflow from your central air system. It is made of heavy-duty steel with a white powder-coated finish that resists flaking and rust for a longer-lasting performance. It fits a rough duct opening 10 inches wide by 6 inches long. It features 3-way air deflection and five adjustable dampers for easy airflow adjustments. Includes (2) screws for easy installation. It is important to check the duct opening size before purchasing a duct or vent cover.
