Through Door Or Wall Exhaust Set Up

I made a through the wall exhaust set up in the garage of my old house. I purchased flexible auto exhaust hose through a friend who owned a service station at the time, and I use metal close drier gates to go through the wall. The little doors on the drier gates kept the openings closed when not in use, and opened freely when in use.

I used two 10 foot lengths of hose, and two metal drier gates. The system served me for about 20 years.

Hope this helps.
