This single-burner Barbeque Box turns your outdoor gas stove into a portable barbeque grill! This grill system will outperform anything you've used. With the patented diffuser plate, you don't have to worry about hot spots. The diffuser captures and vaporizes the grease, infusing your food with a rich BBQ flavor. The cast-iron cooking surface holds in heat and sears meat. A vented lid is included to help keep the heat in. This system covers one burner on the Camp Chef Professional, Sportsman, Outdoorsman, Explorer and OSD Models. It doesn't fit the Sport Utility Stove.
