Specifically designed for the 22.5 inch Weber Kettle Grill, this simple but clever gadget lets you transform your Weber Kettle Grill into a charcoal smoker. Made from 18 gauge stainless steel, the Smokenator 1000 hooks onto the side of the grill, above the charcoal, keeping the heat source contained to one side of your grill. This allows you to control the temperature and create an indirect heat source. Two holes in the top of the Smokenator let you add charcoal or wood chips, and with a refillable water reservoir, you control the amount of humidity. Now you can smoke right in your backyard!
