8" diameter gold Anodized Aluminum ball on a 1/2" threaded rod. Has a locking nut to tighten down onto truck assembly (pulley assembly).
This ball is usually used on a 35' or 40' pole. The ball is generally the same diameter as the butt diameter of the pole.
*Tip!- It is recommended to use 'Locktite' (thread glue) along the threaded rod of the ball along with the locking nut. This will ensure the ball from vibrating loose and falling off the pole
