With Weber’s Charcoal Heat Controller for 22” kettle charcoal grills, you can easily set up your grill for high-heat searing or low-and-slow cooking. Comprised of a cone and diffuser ring, it reduces the guesswork for less experienced grillers and adds a new level of mastery for backyard pros. The cone positions charcoal for up to 7 hours of low-and-slow cooking when used with charcoal briquettes, while the diffuser ring provides even heat across the entire grilling surface, giving you plenty of room for larger foods like ribs, pork shoulders and more. The cone can also be used to create extremely high heat for searing as well as efficient, convection heat for perfectly crispy wings, meats and veggies. Yum.
