ABSTRACT:
A cue stick is provided with an extension assembly inserted into the handle end of the stick. The extension assembly includes a tube having internally threaded end portions. A shaft having a threaded locking end is inserted into the tube and threadably engages a first threaded tube end. Rotating the handle end of the cue stick in a counter-clockwise direction disengages the tube first end from the shaft and enables extension of the handle. Again, rotating the handle in a counter-clockwise direction causes the shaft to threadably engage a second threaded tube end thus locking the cue stick in an extended length.
