The Kamado Joe Classic III includes new innovation, the revolutionary SlRoller Hyperbolic Smoke Chamber insert. Harnessing the power of cyclonic airflow technology to control heat and smoke, the SlRoller insert is designed to perfect the taste and texture of food on low-and-slow cooks up to 260 and is easily swapped out for the original heat deflector plates or removed for searing and grilling at higher temperatures. As with its predecessor, the Classic III it also features a thick-walled, heat-resistant shell that locks in smoke and moisture at any temperature. It also comes with premium Heavy-Duty Galvanized Steel Rolling Cart built to resist the elements. The Series III Cart features a cable tidy for your iKamand probes and a useful accessory shelf which can be used to store the SlRoller Hyperbolic Insert, heat deflectors or cooking surfaces when they are not in use.
