Make your commercial swing hangers last longer by on using the 3/4" Replacement Pendulum for Ductile Swing Hangers - SH160. Swing hangers are how the swing seat attaches to the frame, however, they are not the most stressed component of a swing. The most stressed is on the pendulum. A small oiled bronze bearing, it is designed to take the brunt of the force and is both affordable and easy to replace. While swing hangers are fairly quick to install, changing out the pendulum is faster. Instead of two bolts, its one. And with the ability to simply remove the old anchor shackle from the pendulum and then string up the the new pendulum with the original anchor shackle, its even easier.
