Holy cow, this thing is amazing. I had a second floor laundry hookup but no vent for the gas dryer, only a window. I did some searching around and found this thing. This vent is a solid metal sturdy build, and adjusts to fit perfectly in the window. I did add a bit of foam around the edges, the same stuff you would use to seal off an air conditioner, so that cold air can't seem in from the edges during winter. This thing is a must have if you are looking for an easy way to vent out a window rather than making an entire new hole for a dryer. I tried it at the top and at the bottom of the window. It works either way, but I thought it looked better at the bottom so I stuck with that. The flap only opens one way so no worries about anything coming in.
