Cast iron log rests (in pairs) are a multi-purpose style grate. They can be used in a conventional fireplace as well as in the burning of oversized logs. They are often used to slip over the back legs of andirons to provide added protection from movement of the burning logs. They come in 15", 19", and 21" lengths. Each log rest is 3" wide and measure 3-3/4" to the bottom.
