The Stack Grate Grate from Petromax has many different uses. The grate can be used for itself, as a grill grate over a fire or Finnish stove. In addition, it can be used in a Pot for cooking or baking. It is also possible to stack several grates on top of each other so that you can fry, bake, braise or steam on several different levels. The grill also has the perfect surface to support a Pot over the fire and can at the same time provide perfect grilling lines on your meat.
