This beam is constructed out of ¾” thick Aspen wood and is 6 1/2" tall. You choose the length and depth. Each piece of wood is unique and will have more or less character/knots than the other. It is designed to look like a solid beam without weight. The distressed beams are painted either black or white and have the edges sanded over and a brown stain/wax applied for a distressed look. The distressed beams will not be a solid color. Easy to install utilizing a French cleat mounting bracket which is included. Screws are not included. You will need to purchase 3" screws for the application you will be attaching the bracket to. Wood is considered a combustible material. Heat clearances must be adhered to. If installing over a fireplace, check your local building codes and the manufacturer's instructions for your specific fireplace insert or stove.
