Constructed of durable cast iron, the Broil King (69615) narrow rib roaster with stainless steel elevated grate is an essential Broil King grilling accessory. The Broil King 69615 stands ribs vertically on a stainless grate, saving space and enabling the ribs to roast perfectly rather than stew. Made of heavy cast iron with a durable, porcelain coating that is easy to season and easy to clean. The Rib Roaster fits directly on cooking grids or Broil King Flav-R-Wave. Dishwasher safe. Cooking Tip: smoke for one(1) hour at 225 Fernehiet followed by two(2) hours in the roaster. On a gas grill, roast the ribs at 415 Fernehiet for about one(1) hour (or less).
