This is a galvanized ductile iron swing hanger with a shackle pendulum, opening 1/2″ wide. 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. It has a .51 ID oil light bearing and axle bolt with lock tight nut and accepts a 12mm bolt. The pendulum is 1” wide and has a shackle with a 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 pinhole 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. Do not torque more than 25ft-lbs. when installing.
Sold as each.
