Grill juicy, perfectly cooked steak, poultry, and fish with the help of ManGrate. Sear meats and vegetables with restaurant signature grill marks for a professional look and taste. ManGrate's cast-iron design utilizes radiant heat - instead of convection heat or "hot air" — searing in the juices, but allowing the meats to cook evenly. The smoke rails are the angled ledges on each bar of the ManGrate. These ledges are designed to trap and retain oils and fats released during grilling, and it's these juices that aid in the natural smoking process, giving meats a rich, barbecued flavor.
