Kamado Joe Classic III 18-Inch Ceramic Kamado Grill The Classic III is 18-inches in diameter and is constructed of a thick-walled, heat-resistant ceramic shell that helps to lock in smoke and moisture while grilling. The included Divide & Conquer cooking system is composed of a 3-tiered rack setup that holds up to four additional half moon grates and allows for a larger cooking area up to 510 sq. inches. It also allows varying height levels for different temperature ranges giving you the ability to grill whatever you want however you want. This generation of kamados now comes with a SloRoller hyperbolic insert, developed by researchers at Harvard, which provides even distribution of heat and smoke by promoting a rolling and recirculating flow inside the kamado. The hyperbolic insert is removable and can be placed on the heavy-duty galvanized steel cart under the kamado when not desired to be used. The Amp firebox is made of high-fire, heat-resistant ceramic plates that are capable of resisting damage and breakage from high heat and stress. Sitting atop of the firebox is the 304 stainless steel charcoal basket that allows for easy cleanup and conservation of unused charcoal by quickly sifting ash between the basket bars. Once the ash is sifted, the slide out 304 stainless steel ash drawer gives a means of effortless removal.

The Air Lift Hinge makes opening and closing the lid a breeze by reducing roughly 96 percent of the weight of the lid.
