Rated 4.0 out of 5 by 7 reviewers.
Rated 1.0 out of 5.0 by Roof Cap Flap Horrible. Whoever design this product forget about the weather in East coast. A little wind can cause this Roof Cap Flap, sound like a "Flapper" . Just imagine what happen when wind blowing snow into your Roof Cap Flap and down through your duct in the middle of winter night while you sleep. So don't wasted your time with this product, because once the Roof Cap in place is too late. November 10, 2010

Rated 5.0 out of 5.0 by Easy to install This vent kit went in easy. It attached to the hood and took a couple of hours to do the roof penetration and finish. The low profile on the roof cap looks great. November 1, 2013

Rated 5.0 out of 5.0 by Relatively straight-forward and simple installation. Almost everything for the installation is in the kit. I had to get a longer piece of 7" duct for my installation due to roof height. January 31, 2012
