Thanks for the info. My rod didn't break, it just came unscrewed. The extension handle is a hollow tube that is threaded on the inside. I don't have access to the rod to attach any kind of assembly, I need a hollow threaded tube. As recommended, I did contacted PT and they offered to send me a replacement. Still don't know where to find a replacement but my next try was a shotgun cleaning kit. I don't know if the threads are correct though. May be worth looking at if it happens again, although I'm going to come up with some sort of tether next time.
