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.
Shackle Pendulum (Optional):
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 two inch pipe.
Hangers should be spaced 2 ft from the end of the set and 2 ft a part for each swing. Place the two halves of the hanger around the top rail of the swing set. The swinging pendulum or shackle will be facing downwards. The side bolts are placed with the heads on the top of the hanger and the threads facing downwards with the nuts on the bottom. Using no more than 50 lbs. of torque tighten the side bolts. After tightening, the threads should not be showing more than two threads past the nut, and the hanger should fit snuggly on the pipe. Grease or oil bushings if squeaking noises are heard. Use the H175 to open shackle bolt. Slide chain on the bolt and then tighten in the hanger until snug.
