Bath Fans

Roof vent kit for 4″ bath fan ducts. Best to use with hard duct, better still to change the fan to a bigger one and use 6″ duct work for better flow. Just use this if you are keeping your current fan. Available at big boxes for $15-20. I put a lot of these in during my contracting days. 

Wall vent for 6″ bath fan ducts with damper. Not spring loaded. We have used these, a decent product. We recommend 6″ ducts for bath fans, these vents aren’t available at big boxes. Again, don’t install on a west facing wall or the damper will rattle. Also available in 8″ and 10″ for kitchen fans. 

Standard 4″ wall ducting kit for bath fans. Single flapper is far superior to triple flappers which get stuck open. If you are keeping your current fan, use something like this to vent it outdoors. Available at big boxes for $15-25. Best to use it with hard duct for better flow.
