Broan 644 Reviews
Rated 5 out of
Good ProductThis aluminum vent is vast improvement over the steel Sears vent I installed 30 years ago, which started leaking in the midst of Hurricane Alex. The only problem would be the shipping: it arrived crinkled and bent.

Good ProductOrdered two Broan vent caps - one for a new vent and one to replace a similar unit that was damaged during a roof replacement. These function better than the old one ever did and the bird screen is a welcome feature. The only negative is that the noise of the damper closing is rather loud, but we will get used to it.

Ok for the priceUnit arrived bent up on several corners. This probably due to the fact that its made of very, very thin alum. Fortunately though, easy to bend back it's so thin. Live near the coast so needed alum since galvanized still would rust, but would have gotten a thicker gauge. Also, its opening was a generic, psuedo square shape obviously to fit many different sizes and shape ducts, but would have preferred a 7-8" round collar/opening for a tighter fit/connection. Otherwise works well.
