This tool is made by Sunnen. They are kinda expensive. Big Noot bought it a long time ago. Last time I used this tool I had it a bit tight - and twisted up the whole thing. Big Noot wasn't real happy, but, he fixed it. Now I'm using it again.
Don't fuck it up ! I didn't . . . it worked great !
I'm glad he gave me a second chance on this one . . .
