This vent makes it simple to fine-tune the airflow inside. The built-in levers let you push the dampers open or closed with a quick squeeze, so you can direct warm or cool air exactly where you want it. Once it’s set, it stays put without drifting, keeping your interior comfortable year-round.
No visible screws or hardware to distract from your finish. The grille snaps over the top after mounting, hiding everything underneath for a clean, finished look that blends in nicely on ceilings or walls.
Designed to drop right into a 4" duct opening, this vent connects easily to 4" inner diameter flex ducting. It’s a straightforward replacement or upgrade that fits snug and seals up tight for efficient air movement.
Made from sturdy black plastic, the vent holds up well against everyday use and temperature changes. The two-piece design makes it simple to remove and clean when needed, keeping airflow steady and dust-free.
With overall dimensions of 5-3/8" diameter x 2-7/8" deep (4" deep with levers), this compact vent fits easily in smaller spaces. It mounts with 3-1/8" center-to-center screw holes, and all installation hardware is included so you can get it installed fast and done right.

Great product and true to size!! Thanks again
The web page was easy to navigate and there prices were unbeatable. They also kept me informed of the status of receiving what I ordered.
I purchased this product to shut off heater air flow to bedroom in r.v. It does slow it down a little, but does not close it off completely.
Vent arrived and was as advertised by dimension and material. Installed and worked fine.
It doesn't seal off the vent. Of course the arms are plastic and they did break. But it helps.
I haven't had chance to install yet but I believe it will work as intended. Customer support was excellent. I was contacted to tell me that the color I ordered was back ordered and given an option to wait for the ordered color or have another color shipped immediately. I elected to get another color that will work just as well. I appreciated the information and options.
product was what I expected (just a little too flexible) but OK.
very fast delivery, overall pleased again.
Product is made well but did not work as I wanted it to.
Great product fast shipping will order again
Well made, solid construction. Description is spot-on plus customer service was very good
This works pretty good it does not shut off the air 100% it reduces it to about 30% or so. It was easy to install and should do what I was wanting. Delivery was fast got it in just a few days from the order date.

Had for about a year and still Works great
This round vent was exactly what we were looking for. Could not find one anywhere in town. So I went to the internet, and found this. It is the perfect size and will look great once we get the tile floor in. Thanks!
Valterra Heating and A/C Vent Register - Round - Black great product good price .fast delivery. good communication .thank you
I send everyone your way when needing horse trailer parts.
Fit great, work great, install was a breeze. Bathroom was getting way too hot, and using this vent allowed me to reduce the heater's airflow into it. Would definitely recommend these vents!
This vent is just what I needed to close off front facing vent in my Class C. It definetly allowed more air to be diverted to bathroom where it is needed. It shuts down 90% of air flow. I am ordering another one.
fits perfectly for what i am using it f or
This is a poorly designed vent. Once the base is screwed into the wall/ceiling then you are supposed to snap the vent on. Unfortunately the three snap tabs are wholly inadequate to the task. The vent continually snaps off and I find it on the floor. Probably the only way this will work is for me to drill holes through the vent cover and screw it into the wall. While this will prevent it from falling off, unfortunately it means I can no longer rotate the vent to direct air flow. So, basically not a product I would recommend.
This will work exactly how I need it to :)
Thx I will send pics when done. My travel trailer exterior is complete (I'm building this one from scratch) but the interior will be completed over the next few months. This is the build so far :)
The product seems to be made well and should work fine as a replacement. Unfortunately, I won’t be able to use it until spring when I have access to the camper.
It was exactly what I needed
I actually bought this product for a condo, I couldn’t find anything to work. I had a round floor vent but couldn’t find anything that was actually a vent until I found this product which I thought would work. I ordered , It arrived quickly and worked perfectly! I would order from this company again , I was happy with the product and service.
I purchased four of this adjustable airflow heat vent to replace the Airstream 2015 Classic's vents that are fixed airflow. We had too much air coming out of the sitting area vents and not enough out of the bedroom, hall and bathroom vents. The product is not as heavy gauge plastic but they swivel and control airflow as designed. Also, they are very close to the same size as the vents being replaced so very easy to install. As always, etrailer is very good to deal with and fulfilled the order quickly.
The diameter is SLIGHTLY smaller than 4" and the pre-drilled holes from the manufacturer where SLIGHTLY larger than 4". I had difficulty screwing the unit into place because there wasn't enough panel material for the screw holes to catch to.
Secondly, when closed, there was still a significant amount of air that came through. I was really hoping it would block more air.

This is very good of eTrailer. After owning a year, I received a please review after 1 year of ownership I think thats a better review, than an initial untested review. Anyway, regarding this product, it works fine. But I stand by my initial review that the sizing is off in the wrong direction. It would have been better if the size was slightly smaller than 4
