The Dome Extension raises the Dome allowing you to cook larger portions of food. Included with the Dome Extension is the Chicken Roasting Stand. A great accessory for roasting chicken in an upright position (Beer-Can-Chicken). The stand (and the extra height of the extension) can also be used for smoking racks of ribs. The Chicken Roasting Stand is removable. Place Cobb Pan or Wok on top of the Dome Extension to create a "middle of oven rack" ideal for baking. The Chicken Roasting Stand is designed to fit onto the Grill Grid.
