This family of Pro ranges and rangetops includes dual fuel and all gas products. While the red knobs may be one of the most distinctive traits (you can get black ones)of Wolf Pro cooking products, their real claim to fame is their commercial attributes. In cooking, details make the dish. It's the same with Wolf ranges. Our Wolf ranges and rangetops are displayed in "The Living Kitchen" and you don't have to imagine what the 60" model with a french top looks like because it is on display, along with all the other Pro Cooking possibilities.
