Glider Support Assembly includes a Glider Support, 4 - SH142 Nylon bushing swing hanger, 4 – H165 spring clips, 2 - ½" x 3" lag bolts and the top 1 - ½" bolt for attaching to wood.
Installation:
If your swing set has a single beam across the top, you may need to install a GS glider support. This will produce a four point mounting system. The flat piece with one hole goes on top of the beam and the side with two holes bolted flush against the beam. You will need to drill holes into the beam in order to install the bolts. The bolts should be 2 - ½" x 3" lag bolts and the top bolt should be 1 - ½" and then whatever length your beam is. This bolt needs to go through the beam from the bottom of the beam and have a nut attached to it on the top of the beam.
4 - 2 ½" hangers will go through the four end holes. The nuts should be attached on the top of the assembly with the swing hangers at the bottom of the assembly. The spring clips should be attached to the swing hangers and then attached to the glider.
If you are not using a glider support, and you have two cross beams perpendicular to your swing set, you can attach the four rope and chain pieces to four swing hangers, at least 12" apart, with either, S-hooks, shackles, or spring clips.
