    Rated 5 out of 5 by from Simple solution for venting! I use this wall cap and the black Broan roof caps regularly. They are well made, functional and are less conspicuous than the bright aluminum vents.

    Rated 3 out of 5 by from Broan 843BL 6" Round Duct Black Wall Cap with Damp The quality is very good. It is extremely solid with a gasket around it for a tight seal when closed. Although, there is an area where air can get in when the damper is closed at the location of where the damper door is hinged to the box. I have not yet tried to put this vent unit on my house because of all the snow resulting in poor access to the house. I hope I will still be able to return it if it is the wrong size or if it does not fit. I will update this review at a later date once I have put it in place and have tried it.

    Rated 5 out of 5 by from This is the best vent cap I could find anywhere! If you need to vent a six inch round duct through your wall, you probably won't find a better vent cap than this. Solid construction with a nice durable black finish makes this vent cap better than any others I looked at. A closing flap with a return spring, a bird screen, the black color, and a foam gasket are what sold me on this model, and for not much more cost than the inferrior thin gauge models at Home Depot or other home stores. I'm using this with a 450 CFM inline duct fan, but the spring mechanism for the closing flap is gentle enough to open with a more subtle fan flow rate as well. I did have to adjust the foam gasket a little bit to get a good seal, but most other vent cap options I have seen did not even have a seal at all. With four screw holes, this attached solidly to my home as well. The vent provided a nice snug fit into the hole in my wall I cut with a 6" hole saw. I'm using this to clear the steam from boiling a 10-gallon pot of liquid (for making beer) in my basement. The flap opens as soon as I turn on my fan and then shuts and holds itself closed when not using the fan. I also love that the bird screen keeps out birds and mice. If I had to buy one of these again, I'd get this same model.

    Rated 5 out of 5 by from solid product The vent cap is well constructed and solid. The animal screen does pop out however. This should not be a problem with normal use. It did come out when I was installing it. Nice thick gauge metal and it appears the paint is baked on.

    Rated 5 out of 5 by from Exhaust vent I found this vent to be of high quality and just right for my needs. Compared to the cheaper products I found at the big box stores this was a no brainer. Plus the price was substantially less than comparable vents at local plumbing supply outlets.
