Product review (1 stars): Poorly engineered
Ordered to connect to the wall vent that pipes the dryer exhaust out of the house. Product arrived on time, however it was impossible to install. The directions said it was designed for exactly what I ordered it for, but I was unable to install it. Simply imagine pushing a 4" pipe INTO a 4" pipe. I followed the directions, cut the exhaust pipe as directed and attempted to widen that opening to accept the new elbow connector. No matter what I did this action was impossible to accomplish. I even attempted to reverse the action and mount the elbow OVER the exhaust pipe to no avail. In the end this was a waste of an hour or so of my life and many cramped filled moments behind the dryer. Just a bad design.
