Flapper construction:
Cut aluminum vinyl coated sheet to size and cut hinge rod
Bend aluminum sheet around rod
Install rod into vent opening
The rod I used was threaded and came with a threaded fastener. The cut end of the rod was cut was die cut to accept the same fastener. You could just use a nylock nut for the same purpose and use a piece of threaded rod stock.
Easy project took me about two hours even with the super techno spring and cable system I was going to use. I didn't use the cable as I found an easier way to hold the vent open, I removed the spring. The fan blows the flapper open when on.
