This is for a 6" black plastic minibutt with female thread, really a handy item for any snooker/pool player. Can be screwed onto the shaft to make a "shorter cue". This is ideal for when you get stuck in a spot where you cant get into cue with a full length cue.

To avoid disappointment, please check your cue first before buying to make sure it will fit.
