*by A***R on 8 March 2025*

This company puts out "quality" items Something we dont see to often anymore. This item works great when exhaust fan turns on and closes nicely when fan is off. I like the rubber gasket Keeps cold air from coming back into house BigBox stores carry similar item BUT not as well made and more money Highly recommend
