Broan 634 Reviews

Rated 2 out of 5 by from 8" Range Hood Roof Vent This hood was to be used with an 8" duct pipe. The vent should have come with an adapter to mate directly to this size pipe. The other (2) 6" roof vents (Broan model 634M) that I purchased had 6" collars to mate with the pipe. This would have made a far more secure, and better sealed attachment to the range hood duct. As a result, I needed to fricate a collar that could be attached to the underside of the roof sheeting.

Rated 3 out of 5 by from Did The Job Did not fit the 3-1/4 x 10 without snipping inside metal off and it did not sit down flat because of metal ridges. Not really satisfied with fit, but could find no other product for that size roof cap. If it had fit it would have been a good product.

Rated 1 out of 5 by from Roof cap This roof cap does not make a closed connection with either an 8" round or a 3 1/4 x 10" with out an adapter. It is roughly a 10" square. I had to have an adapter made to attach to attach to the attic side to connect the duct. Broan didn't show any other part needed to complete the vent connections on the schematics.
