Two cooking grates stacked vertically give this smoker ample space for smoking different types of food at once, so meats, vegetables, and seafood can go in together rather than in sequence. Each grate measures 13 by 13 inches and lifts out, which facilitates easy cleaning instead of scrubbing inside a fixed chamber. Heat and smoke circulate through the vertical body to ensure even cooking and a rich smoky flavor across both levels.The two-pan system underneath is what makes long smoking sessions work. A charcoal pan generates direct heat and smoke once lit, while a water pan above it adds moisture that prevents the food from drying out over hours. Each pan has an 11-inch inner diameter. It is worth noting before the first cook that charcoal and water are not included, so both need to be on hand at setup.Access and control are handled without wrecking the internal temperature. Separate doors mean water or charcoal can be added without opening the top chamber and releasing accumulated heat, and those doors lock shut to prevent unwanted heat loss between additions. A built-in thermostat shows the inner heat so vents can be adjusted fast, and the adjustable air vents themselves manage smoke and heat for perfectly cooked dishes.The frame stands 19 by 18 by 40 inches in metal and weighs 39 pounds. Elevated legs ensure stability for safe usage, sturdy bracket holders hold the pans secure, and side handles make the body simple to reposition. Two cooking grates, a water pan and bracket, a charcoal pan and bracket, and an instruction sheet are included. Assembly is needed.
