Query: What is the thread size?

This thing attaches to my 3" pellet stove flue pipe brush but how do you attach it to the imperial fiberglass rod lengths? It seems to be 1/16th inch pipe thread, which is impossible to find at hardware stores. Finally, I had to duct tape the thing to my fiberglass rods to get the job done. I'm spending money, making sure I'm going with one brand name for everything and I have to duct tape the products together to get the job done? Sorry but that doesn't cut it. I'd look real professional going to the job site with a duct taped chimney sweep tool. Maybe there is an adapter available. It needs to be more accessable than what I've found to be the case. These products also need to list thread size as well. Many chimney sweep brushes are 3/8", 1/4", 1/2", yet have no listing on their sizes.
