The short pin allows you to lock the pole on static mode, and remove for spin mode. The short pin is 1 inch long and is used for all of our spinning poles: Extreme pole, permanent studio and club poles, and the platinum stage pole.
The long pin is only used together with the studio base, which is drilled into the floor, and the long pin drops into the floor though the designated hole in the base and prevents the base from shifting. approx 1 1/2" long. Used with permanent studio base only.
Please note, the long pin is NOT for spin/static use on any of our poles. For spinning and static function, please use the short pin only.
