Turn your gas grill into a charcoal grill/smoker. With the Napoleon Cast Iron Charcoal Tray, you can now enjoy the flavor of charcoal as often as you want. All Napoleon grills are made to withstand the intense heat produced by charcoal. Fits easily into your gas grill just above the burners, in place of one sear plate. Add lump charcoal, replace your cooking grids and start your grill. Once charcoal has starter, turn the burners off and now you're ready for old-fashioned charcoal cooking the simple, modern way. And for those who like a touch of hickory or maple, try adding some water soaked wood chips to add that extra flavor.
