This is a very nice metal stamping. It is rigid and will not deform upon installation.
However , it has a ridge around the outside diameter so a gasket or calking will be required
And , because it is a stamping the fins do not overlap the openings. This means that if you mount this on an angle other than 90 degrees vertical and get a horizontal rain some water may enter the compartment.
I like it and will use it anyhow. My mounting gasket will have a small opening gap at the bottom for water that gets thru the louvers to drain out.

Did what I wanted it to do. Good quality product for the price.

Well made, worked great for what I needed it for

Nice product.

Fit over my existing vent holes and worked. Needed to cover up the Broken plastic vent covers.

Believe it or not, it’s not easy to find a good-quality stainless vent cover. So I am pleased to report that this is one. This is a serious vent cover.

These are made of pretty solid metal. The polish job is very good. I like them.
