Description
xProduct Overview
The 12"W x 6"H white aluminum curved blade supply register carries supply air into the room through a ceiling and sidewall opening. Extruded aluminum resists rust in humid rooms, a stronger choice than lightweight plastic covers. A built-in damper adjusts or shuts the airflow, so comfort can be set room by room. Select this curved blade supply register by its duct opening size, not the overall face size, so it seats correctly on the first fit.
Key Features
- Aluminum construction: Aluminum keeps the curved blade supply register rigid during installation and resists warping over time.
- White finish: The white finish coordinates with common flooring, trim, and hardware.
- Adjustable airflow: The built-in damper controls the volume of air (open to closed).
- 3-Way air pattern: The 3-way throw sends conditioned air where the space needs it.
- Right-fit sizing: Ordered by duct opening size, this curved blade supply register matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?
Choose this curved blade supply register if you need an adjustable supply-air vent for a ceiling or sidewall opening. This curved blade supply register carries supply air and mounts on ceiling and sidewall surfaces. It is not designed for floor installation or foot traffic, exterior or outdoor use, dryer exhaust venting or use as a filter-holding return grille. Confirm the airflow function against your HVAC layout before ordering.
How to Measure for This Vent
Remove the existing vent and measure the width and height of the duct opening, not the outer face of the old cover. Match those two numbers to the nominal size above. The overall face measures 13-3/4"W X 7-3/4"H.
Installation
Position the curved blade supply register over the duct opening with the louvers facing the room. Confirm the frame sits flush against the ceiling surface before marking the screw points. Secure it with the included screws without overtightening, since excess force can distort the frame.
What's Included
- 1 x curved blade supply register
- Mounting screws
Ductwork, wall anchors, and installation tools are not included.
Care and Maintenance
Clean the curved blade supply register with a soft, damp cloth and mild soap. Avoid abrasive chemicals that can damage the white finish. Dry the surface to keep moisture off the metal.
