Well built
We’ve used various products from other sites, the switched one day when our supplier was out of copper exhaust vents… will continue to buy from Famco as they stand by their products and have had nothing but positive feedback from houses we’ve installed.

Nicely built but the screen should be better secured.
Nicely build but the screen is simply placed and not secured. Any minor movement dislodged the screen. I went to the local hardware store and purchased copper wire. Then I needed to drill holes in the into the unit to “thread” the copper wire to secure the screen. This worked great. The vent looks great and is working well.
