OK all. I just purchased everything from local Lowes. All Supervent parts. I have a cathedral ceiling and need the ceiling box. However, I have a question with the install. My wife wants all black pipe being exposed to the inside. With Supervent the instructions show that I am to drop the stainless chimney into the box and have a small bit being exposed. She will not like this. Is there a trim piece or adapter that will hide the stainless?
