The HF-33 Side Lock Hanger is specifically intended for use on outside beams when a mechanical screed machine is to be supported by the bridge overhang. The 45º/90º heavy duty free fit end clip is adjustable from the top side of the form, using 1/2″ coil rod or coil bolts. This hanger is suitable for either steel or concrete beams. The 90º side lock feature prevents the hanger (when under a load), from sliding towards the 45º edge.
