This aluminum ball ornament is gold anodized with a spindle threading.
5/8" spindle threading. Make sure your truck assembly accepts 5/8" ornament threading. Our truck assemblies accept the smaller 1/2" threading by standard. If ordering a truck assembly from us for this ball, make a notation in the comments when checking out that the ball and truck are being used together so we can special order the correct threading on the truck for you. Call if you require assistance.
