This fireplace grate made of durable cast iron will keep your burning logs from rolling out your fireplace, while you add more logs when needed. This fireplace grate is perfect for small pre-fab and wood burning fireplaces. By raising the firewood off the floor of your fireplace with these fireplace grates not only create a hotter fire but protect the fireplace from direct contact with flames. These cast iron fireplace grates have optional sections that can be added. Each section is self supporting and will increase the width of the grate by 7". These grates work very well in conjunction with the firebacks and fireback boots.
