Broan 634M Reviews

Rated 5 out of 5 by from Perfect roof cap It can be a bit expensive but it is very sturdy and very good looking roof cap. The door is a little bit light and I glued two pennies to the door to make it heavier.

Rated 5 out of 5 by from it works whats to say about a metal roof cap. It works, has a damper and looks like it will last. Not at all sexy, but important none the less.

Rated 5 out of 5 by from Broan 634M What is there to say - it's a 6" vent. The only complaint I have about it is that the neck part that sticks down through the roof is too short. If you have 3 layers of shingles, you need to connect the vent pipe to it before attaching it to the roof, otherwise you will not have enough neck sticking through the roof to attach to without fabricating an extension. Hard to describe, but trust me, connect to the vent first, then push through from the outside. :) Venting Direct has the best prices I found anywhere on this item - by far. Shipping was fast too. Highly recommended retailer!

Rated 5 out of 5 by from Quick and easy solution for terminating vertical duct from range hood. Simple installation with clear instructions. Nice look on the roof.

Rated 4 out of 5 by from well built I originally ordered this to use with a bath vent, but after the bath vent turned out to be smaller than advertised, I used it for my new range hood. It's a simple design and the screen is easily removable. I believe the damper is also replaceable if it were to be damaged. It could be improved if there were to be some sort of noise damping to keep the sound of rain from conducting into the kitchen. I'll probably solve that with a coat of rubber or something next summer.

Rated 5 out of 5 by from Dust Roof Cap The dust roof cap is great. Easy to install, no additional parts were need. Completely satisfied with product. Shipping was at the speed of light. I never expected to receive this as quickly as we did. Wonderful experience all the way around. Thanks so much.

Rated 4 out of 5 by from Good...but could be better First I'd like to highly recommend VentingDirect.com because my order was processed and sitting at my door within two days. Overall I'm pleased with the vent, however the vent flap does not seal properly on all sides and is basically useless. This is because the vent flap metal is very thin and has a curve in it which does not permit a good seal. I added extra gasket material on the sides of the frame that help, but the only real fix is to use a heavier gauge steel or plastic material that does not curve. I painted the vent to match my tan colored roof and it came out looking great. The inside collar is short, but it does work unless you have a very thick roof penetration area. Overall I'm happy with the vent, but the flap & seal design was a disappointment on an otherwise quality built product.
