This is a galvanized ductile iron swing hanger with a shackle pendulum. These hangers are cast in two halves. The lower half of the swing hanger body has a shackle pendulum with a sintered bronze bearing incorporated into it to reduce wear. These bearings do not need to be oiled as the bronze is impregnated with oil. The pendulum is 1” wide and has a shackle with bolt so that there is no need for a connecting S-hook. The shackle pendulum is tamper resistant. It requires an allen wrench with a special pin hole head. The two halves of the hangers are bolted together with a 12mm carriage bolt and a hex lock tight nut. The pendulum is held to the hanger with a #12 axle bolt with a long shoulder, so the bearing does not ride on the threads. It also has a lock tight nut. This hanger fits a standard schedule 40 three inch pipe. Tensile strength is 5000 lbs.
