Each end of the single guide bar is bolted to near an end of a support bar by a fastener through the slots so that the bridge is formed. In use, the bridge is positioned at the entrance to the fireplace with a lower end of each support bar supported on the floor of the fireplace. The single guide bar is positioned along the top edge of the entrance and a first course of files is set against a front surface of a wall above the fireplace with a lower edge of each tile arranged parallel to and along the horizontal edge. A marker clip is snapped onto the guide bar and moved along to position each successively laid tile.
