The HF-23 Exterior 45º/90º Frame is intended for steel or concrete beams and is typical of exterior overhang forming. The 45º/90º Free Fit Hanger is adjustable from the top side of the formwork and uses 1/2″ coil rod or coil bolts as the 45º end section supports the overhang bracket. Bolt centerline must be within 3/8″of beam edge. The HF-23 Hanger is desirable when no haunch condition exists on the interior side.
