Correct size floor vent/register

Hello everyone,

My main bedroom has a floor vent cover/register (I think I'm saying correct--new to vent heated/cooled houses) that is older than the other rooms. I think this is because the previous owner had large furniture that was difficult to move and never bothered to get it replaced when the others was replaced.

The issue I'm having is vent adjuster doesn't allow enough air to flow due to it being narrow but fills the vent cavity compared to the other style where there is just the open/close bar.

I'm posting as I'd like to replace the one in my bedroom to be the other style (pics below), but I don't know what size to order. It is an angled style.

The actual vent dimensions are: 12"x3.5"x3.25". The current vent cover dimensions are: 13.5"x7"x3.75".

There is no branding on my vent covers. Any recommendations on where to buy and what the correct sized cover should be? Thanks in advance.

Current style (what I want to replace):



Vent style I'd like to install (this is in the other bedroom and all throughout the house):

 

You just need a cover that fits. The performance is limited by the duct in the floor so changing the register/grate isn't going to have much affect.

 

Actually, that's the part you cannot see. The old/current vent adjustment fins block the airway. Only a very shallow angle to allow air to pass and if I try and open it more, it blocks the airway more. Having the other style would indeed help.

 

Did some more researching online and I think what I need is a 12 x 6 baseboard register with damper to match the other rooms. Nothing else is closer in actual dimensions to the older style that I am currently replacing, so I'll just order one of those and see if I need to make any minor cuts to the molding.

​​​​​​​Thanks.

 

Those angled vents aren't all that common, so you won't have a huge variety of sizes. I think you're on the right track with a 12x6 and adjusting the molding as needed.

 

I finally got around to installing the angled register. I misplaced my one oscillating tool straight wood cutting attachment so I had to buy a new kit. My cut was off just a little, but doesn't look too bad. The only thing I noticed that I didn't realize at first is that all the other registers have vertical slots, and this one has horizontal. Hopefully that won't matter with air flow as that is what my goal was with improving, but time will tell on a good warm/hot day with the AC blowing, then come fall/winter with the heat blowing. Pics for the completed job is attached.

Cheers!

 

Honestly, it doesn't look like you've increased the open area over the one in your first photo.

 

The angle of the new cover and the old is about the same, but the airflow should be much better because in the old one, it had multiple adjustable blades that when I tried to open them, they blocked the vent more. It's kind of hard to explain, but I took a pic of the inside of the old cover to show what I mean. The horizontal vs vertical fins make a difference too, because I think I would have made out better with vertical fins, but I couldn't' find one reasonably priced in the size I need.

On the new cover (and like all around the house), the single blade open/close allows me to open the damper and allow more air to flow. I think the issue was the vent in my main bedroom was either too narrow, or when installed wasn't as deep as it could be for some reason. Standard wall depth of 4 inches plus sheetrock, but for some reason, the old cover didn't open that much.
