Abstract: In this invention a hanger is used for attaching cross members to a vertical support structure. The hanger is made up of a box part that includes a mounting surface, two spaced distal openings and a central opening that is located between the two distal openings. The distal openings have been adapted to accommodate a fastening device. The central opening is designed to accommodate a cross member. When in use, the mounting surface of the hanger is placed against a vertical support structure and secured into position using the fastening devices. Once two hangers have been secured, a cross member is slid into and through the central openings of the two hangers, being supported by the hangers. The cross members can then provide a base onto which a platform may be assembled for such uses as hunting, camping, or other outdoor activities.
