Our cast iron bars sit at the front of the firebox and help to stop any logs or coal from falling out of your small stove when you open the top door. They’re also great at helping to prevent logs and coal from burning against the glass, which will cause the glass panel to blacken over time. If you’re going to be burning larger logs or a good-sized pile of coal, then we would recommend you to purchase our cast iron coal bars, which provided added height and protection at the front of your small stove.
