The Standard Modern Swing Hanger is offered individually as replacement parts or to build your own swingset. These hangers will fit round posts and are available with a standard or shackle pendulum (the area that holds the chain). The Standard Modern Swing Hanger requires use of an s-hook or shackle to attach chain to the hanger, unlike the Shackle Modern Swing Hanger, which includes a shackle built-in. Request the Standard Modern Swing Hanger for your commercial swing replacement.
