The CSH-TZ concealed stringer hanger provides a method of connecting a stair stringer with a hidden hanger. The seat of the hanger is adjustable to match the slope of the stair stringer. The reversible design allows the connector to be used on the left, right or interior stringers. The CSH-TZ may be used with USP's SCA stair angles for a complete, easy-to-use stair framing solution. .
