    • Works great!
Size: 6" to 4"
Needed to convert a 6 inch duct from an exhaust fan to a household 4 inch dryer port. This thing fit over the exhaust fan port with very little issues, but enough that it was going to stay in place. The 4 inch metal ducting went over the other end with no issue.

    • Perfect reducer for bathroom vent project
Size: 6" to 4"
New bathroom vent fan has six inch outlet; too big to easily run an outside outlet, so reduced to more manageable four inch with this.
