Dryer Vent Flap (Yet Another)

I needed a dryer vent flap that had a little weight on the outside edge. My vent flap housing was a beat up by a dog chewing the old flaps and the holes were a little wonky. This vent flap has some additional weight built into the outside edge that helps the flap close after the dryer shuts off. The added weight is not “too much” that the air from the dryer cannot open the vent at all.
