This coupling comes with an insert to reduce the top of a pole down to 1/2" pipe thread. This piece is designed to work on our Light Ring Towers to place a star on top or it can be used on a tree that you design. It comes in 1 1/4" or 1 1/2" thread.
You do not need this if you are purchasing one of our standard hook Heads or a pulley head, each of these has its own star holder built in.
The Star shown in pictures is not included. Must be purchased sepertly.
