Product review (5 stars): Extra 2-4"
Purchased two of these and they saved me 2-4 inches for my washer and dryer install which was crucial for the tight space I had to install them. My dryer outlet is behind where I installed my washer, and the standard aluminum 4" hose I used originally would kink when I forced the washer back as far as needed. No problem whatsoever with this item.
