Its simple and modern design, this 24 In x 24 In fireback adds a contemporary style to any fireplace. The most efficient way to heat your house, the fireplace fireback absorbs the heat and then radiate the heat directly into the room. Constructed of 14-ga., 304-alloy stainless steel, these Radiant Firebacks weigh about one sixth the weight of a cast-iron fireback. Each fireback has a gentle curve applied to its back. This pre-stresses the fireback to minimize warping. This fireplace fireback features slotted support legs that allow you to adjust it to three angles: 65, 75 and 90 degrees. The legs are 1" high, 2 3/8" wide and 9" long.
