For use indoors or out, this ASTM E136 non-combustible mantel shelf was cast from a patented molding material using a found piece of Limestone capturing, to perfection, the nuances and subtle details of this age-old stone. The chiseled front edge springs to life through the artistry of a meticulously hand-painted finish. Made in the USA, this shelf has a 9-inch depth allowing for ample room on top for personal effects. Due to the natural imperfections captured from the Limestone, the top of the mantel shelf will have natural offsets and depressions and the dimensions will vary slightly, i.e. shelf height and depth will be marginally different across the entire mantel. 5”H x 9”D 100lbs. When mounting your mantel, adhere to the “clearances to combustibles” specifications of your fireplace insert or stove.
