This is a remix that replaces the sliding jaw with one that accommodates the placing of a billiard cue. Similar to a q claw but utilizes clamps instead of weight. There are two versions, a single cue clamp and a triple cue clamp. Both share the same bar and lock.

With the triple cue clamp you can use either one or two bars, but I find two bars are the most stable. Both would probably benefit from a piece of rubber stuck to the jaws or dipped in plastidip.
