Our range hoods install perfectly in 12" standard cabinets. We do not manufacture any specific model for 15" deep cabinets, however, some of our contemporary arced models look beautiful in the deeper cabinets. If you install the hood back against the wall, be careful to duct the hood to vent outside or if it's being installed to recirculate back into the kitchen, mount the hood forward with some kind of non-flammable panel to cover the 3" gap and protect your cabinet. The hot air discharges into the kitchen from vents at the top and must not be trapped under the front of the cabinet.
