The single burner BBQ Box (model BB100L) turns your outdoor gas stove into a portable BBQ 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 the heat and sears the 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 does not fit the Sport Utility Stove.
