Oklahoma Joe's This grill combines superior control elements with heavy-duty, high-capacity grilling. It is rugged steel construction and thick cast-iron grates create supreme sears for years to come. And between its height-adjustable charcoal tray and large air dampers, the judge lets you choose between grilling over high heat or cooking low and slow. Since charcoal can be messy, the removable ash pan lets you clean quickly and get back to what matters.
