Product review (4 stars): Great idea that works
I installed a new dryer vent at about waist height instead of near the floor. This quick disconnect allowed me to use a much shorter vent hose because I could now push the dryer in most of the way to it's final position and then reach back and quickly connect without screwdrivers and bad language. Made out of heavy plastic. Slightly larger diameter on wall flange would be nice and depth on hose flange. I had to cut an oversize whole due to tools available and wider flange would have helped.
