Product review (5 stars): Just what I needed
I actually liked this because I wanted to vent my dryer straight out the wall, instead of having a flexible tube get smashed behind the dryer. We cut the hole in the wall, attached this to the dryer, pushed the dryer against the wall, and this went outside, then we pushed some of it back in, cut off the excess with a metal saw, and put an outdoor cap on it. No bends to reduce my dryer power or clog. It worked wonderfully!
