Well made dampered roof vent!
We use this product for the venting of bathroom and whole house exhaust fans that we are ducting with 6" rigid duct. Generally we remove the 7" collar and terminate the 6" duct through the roofline creating a flange by making a 1" notch all the way around and then folding the 1" tabs down and screwing them down.

Ridiculous requirement to buy a minimum qty of 6
What home owner or for that matter most contractors want to buy a minimum qty of 6 of these items. Ridiculous.

Bathroom Fan Vent
This is a great vent for a bathroom fan. The attached pipe makes it easy to attach the vent pipe to. I would not recommend using the screen if using it for a dryer vent.
Thanks for the feedback. Glad you were satisfied with your Master Flow purchase.

Great experience
Great roof vent. Important to remember to remove the screen or lint will back up. My dryer died after 1 year so I had the screen removed when the lint plug was removed.
