Product review (5 stars): PERFECT REPLACEMENT FOR DRYER VENT CAP
Replaced a plastic dryer vent with this; loosen vent clamp, slip this into dryer vent pipe, tighten clamp couldn't be simpler Wrapped some metal duct tape around connection for added security; this cap has a metal flap that opens when dryer is running and closes when it stops. Sprayed it Almond to match the house color. Nice sturdy construction. .
