Two dampers on Dryer Vent?
Is it out of the ordinary to have a second damper on a dryer vent?
There is a standard plastic damper on the vent cap on the side of the house.
I thought maybe a glavanized one in line with the 4" duct would be added protection against critters getting in.
How is your dryer vent set up in regards to dampers/critter management?
