  1. Nice Copper Vent. Good Price. review by Brian on 2/3/2016

    I shopped around for these on the internet for quite some time. I found this copper vent ~30% less than the competition.
    Only reason for 4 stars and not 5 is that while it was packed well, and shipped in a big wood box, it did come with a small small ding in the top of the arch. No one will ever see it from the ground.
    Shipping was pretty much on time even though it came from very far and the east coast was hit with a major snowstorm.
    All in all - great vent - great price.

can you make a half round louver painted metal?
We do not make our vents out of painted metal. The reason is we solder our seams and this would blister the paint.

Please explain from what point to what point is 18".
18" would be the diameter of the circle. So 18" wide and 9" high. Or 24" wide and 12" high for the larger size.

I would like to see a view from the back of the dormer. I will be installing this on a steel roof. The back of the dormer will determine how I will have to cut the steel roof so I can slip the back flange under and make it flush with the back of the dormer.
