Before ordering I did extensive measurement and discovered old ductwork to outside. I was able to construct a wall mount in front of an unused window over the range, connect the Hauslane to the structure and to the old duct work. The range hood works beautifully, especially with a family member who does a lot of high heat range cooking. Smoke and odors are quickly removed from the house while cooking. The really attractive hood inspired some redecorating in the old kitchen. We are very happy with the purchase.
