Product Overview

The 6" Neck white steel round ceiling diffuser carries supply air into the room through a ceiling opening. Powder-coated steel resists dents and rust for years of use, 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 round ceiling diffuser by its neck size size, not the overall face size, so it seats correctly on the first fit.

Key Features

  • Steel construction: Steel keeps the round ceiling diffuser 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).
  • Right-fit sizing: Ordered by neck size, this round ceiling diffuser matches standard duct dimensions and cuts wrong-size returns.

Is This the Right Vent for Your Opening?

Choose this round ceiling diffuser if you need an adjustable supply-air vent for a ceiling opening. This round ceiling diffuser carries supply air and mounts on ceiling 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

Measure the round duct or collar the diffuser connects to and match it to the 6" Neck neck size above. Do not measure the outer panel. The overall face measures 9-15/16".

Installation

Position the round ceiling diffuser over the duct neck 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 round ceiling diffuser
  • 1 x butterfly damper with key handle
  • Mounting screws

Ductwork, wall anchors, and installation tools are not included.

Care and Maintenance

Clean the round ceiling diffuser 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.

Mounting holes are perfect

Mounting holes for the diffuser to the damper line up perfectly. My pics shows reverse installation of the hardware - when done correctly, the damper bolts will have white heads on the ceiling side. 4 stars for the damper turner being hard to work, but the product is perfectly serviceable.A higher quality damper diffuser combo utilizes the damper turner to mount the diffuser to the damper, but this isn't much more work. The damper turner seems a bit long, so we'll see during installation if it needs to be modified.That won't happen for a while, so feel free to ask if I forget to update this review.

Perfect!

For a while I’ve been working on replacing all the vents / diffusers in our home that was built in the 80s. This diffuser fits perfectly when replacing an already existing one. I love that this comes with the damper as well. So this order of the whole diffuser and damper kit was used to replace an older one that was looking rather nasty on the outside and inside and was also missing the plastic handle adjustment piece. So now it’s looking new and clean and I feel better knowing that I’m one more step towards breathing cleaner air. Goodbye dust and rust!

Get it if you need it it works

Fit right on perfect take the old one off put this new one on. They're golden. Worth every penny. I did a renovation and I didn't want to change the look only the location and I use this instead of the old junky one I had. It looks beautiful. Now how long is it going to last? No idea but who cares they're only like 10 bucks so get one if you need it.

No instructions, inappropriately sized screws. Otherwise a nice looking damper/vent

Looks great, but should come with different screws. If you look at the image, there are white and black screws of the same size, but the holes on the damper are of two different sizes. The smaller holes do not fit the included screws. To try to get the damper to fit i had to use smaller screws to keep the damper in place while i used the larger screws to hold the vent portion onto the rest of the damper/duct/ceiling. It would be much better if it came with instructions or other screws. It looks nice, but due to the lack of hardware, it looks like it wasn't installed perfectly/correctly. Otherwise, it's a great looking vent and it looks like it will do the job well!

Vent cover are much larger than

I ordered the 8 inch with damper / defuser the defuser part seem correct but the vent cover was almost a 20 inch cover . It fits but it is very large for some of the smaller rooms such as the bathroom or hallways.
