Stainless Steel Convection/Cook ChamberKeep the inside of your smoker sparkling clean and rust free with a stainless cook chamber. This includes the walls of the cooking chamber, the rack slides, the racks, the water pan, and the slide out water pan holder. Use the options on the right to upgrade the heat diverter, face frame (flat surface the doors sit against), back side of the doors, or the entire door to stainless.
