When placing your Kamado Joe directly on a solid base for a built-in application, the grill must be placed on these ceramic feet. The feet elevate the Kamado Joe, allowing air movement directly under the grill to help dissipate the heat.
18-inch grills (Classic Joe) use 3 feet.
24-inch grills (Big Joe and Pro Joe) use 4 feet.
Space them appropriately so the grill does not rock when opening/closing the dome.
