Broan 643 Reviews
Rated 4 out of
quality productThis wall cap was the only one available in 8 inch so I didn't have any choice however, it is well constructed. I have two minor complaints. There is no sping to keep it from flapping in the wind nor is there any rubber or foam to decrease the noise when it flaps.

Prompt and EasyI ordered a vent wall cap and it was a very easy purchase. It was a good price and arrived promptly. I am very satisfied and would buy here again.

Very noisy in any windThe banging noise from the damper flapping in the wind is annoying to say the least. Will replace this wall cap with one outfitted with a spring to keep out the wind.
