Where can i get a plastic or metal vent from?

[DannyF]

Good Evening,
I have a hole in my bedroom wall for an airvent that measures 10x9inches. I am having trouble getting hold of a vent to cover this hole. The biggest vents i can find measure 9x9inches. Does anyone know where i can a big vent from to cover this hole? 12x12 or similar?
Cheers Danny.

Local hardware shops are a good place to try, should have a few where you live, or maybe screwfix.com

I can only find 9x9 inch vents!
I guess i may have to reduce the size of the hole somehow.

You're right, they all seem to be 229x 229mm

Perhaps it was intended that an air-brick should be mortared in, and allowance left for the mortar.

Found this website who do 12x12inch metal hit and miss vents.
