Product review (4 stars): Difficult installation
I just finished installing this - it was not an easy project! In my case I only needed a few inches of the 0-18" range which necessitated cutting down the box. Fortunately I had the snips to do it and have worked with sheet metal before. I then sealed up all the seams with foil tape - otherwise I'm sure it would have leaked out humid air and lint. The couplings were not of the best quality and it was a struggle getting them connected to the dryer and the vent, especially in the tight space behind the dryer. One other thing, the kit came with 2 band clamps so don't waste your money buying them separately as suggested.
