Product review (1 stars): Good Luck with the Dryer Dock
Looks so easy to install, it is not!!! The flange opening is just about 4 inches and the vent pipe is 4 inches, so it was not possible to slip the dock inside the pipe. I bought two aluminum vent pipes, neither would allow the flange to slide in. I eventually gave up and simply glued the vent pipe inside the wall. I donated the Dryer Dock to Goodwill.
