  • Patent number: 4005942
    Abstract: A wood framing hanger including an angle element having a top flange adapted for connection to the top side of a wood structural member and a lower depending flange formed at a substantially right angle. The hanger also includes a stirrup element having a seat and right angularly related side flanges. The stirrup flanges are one half the width of the seat and welded at their upper edges to the depending flange of the angle element. The top flange angle element is formed with nailing tabs at one end and a welding tongue at the other end. The top flange configuration is devised as a nested progressive for high production automated tooling. Likewise the stirrup element is designed for high-production automated tooling and any size may be made from the same single die system using different width coil stock.
