Cast Iron Wok Station Ring turns your Napoleon Rogue® or Prestige® grill with infrared side burner into a wok station. Simply place the ring over your grill’s infrared side burner grid. The special contoured design fits Napoleon’s Stainless Steel Wok. Because of cast-iron’s conductive properties, the Wok Station Ring provides even heating up the deep bowl of the wok for even better stir-fried results.
