This 19mm Male Tool holds the 19mm Female Glass. Comes with a 10" SS Tube.
We cannot guarantee that the ground joint holder will run perfectly true. The variable is the Stainless Steel Tubing. We have no control over this.
For best results , try running the ground joint holder within 2 inches behind the graphite head.
For a perfectly true running joint "guaranteed" , try the 12" Graphite ground joint holder
