Product 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.

)))) METAL GREAT VENTS DEFINITELY FIVE STAR(((((

Are these are the best these are what I had original and they got replaced and I was not happy! And then I found these and then they got replaced again with these! These are metal the inner flaps go the way you want them to go! The direction of the air flow with the vents on the outside! I had my air conditioning system duct work everything replaced in the home and they put these plastic drop down I'm not sure what they are I piled them up and up box and told the AC company that could come get them and I re-replace all the AC vents with these the proper one that are actually metal and you can direct the flow of air how you like it! They are five star easy installation very easy to adjust the air flow and direction where you would like it to go.

Nice quality but could use some adjustment on the top plate length.

Really like the multi-fin openings. We purchased a screw-down one because my toddler kept deciding to lift up the vent and chuck his toys down there, so this was the best solution. The one downside I will say about this product is that the screw holes should be a bit more outward or the length should be extended another 1/2" on each side. I barely managed to screw them into the floorboard and had to go in at an angle even with the correct measurements (10x4 is what I bought).

Great quality!

Same quality at half the price of my local home improvement stores. I installed these throughout my house during a remodel and I am very happy with the quality. They were easy to install and come with white painted screws for installation. They are fully adjustable and even have a damper to control the amount of air flow. I highly recommend this product

Great for redirecting airflow

I had a vent that only blew straight beforehand and that would freeze the person on the couch when the air was on. I wanted something that would redirect the air sideways some to prevent this. I measured the inside of the cavity and this unit fit perfectly. The scree holes into the ceiling even lined up with the older vent. The build quality feels very high and does exactly what I want with the air flow. The reason I did 4 stars is because of how difficult it was to move the individual vents to start. They were folded on top of each other and needed a tiny screwdriver to separate them.Also the lever to control air flow is behind the vents.Overall we are thrilled with his change and the vent makes no noise!
