Starting collars for round?
I know starting collars are to tap off of square duct but is there such a thing for round metal duct. The reason I am asking is because I have a 12 inch supply that I want to take run some duct lines off of. I see that A saddle is about the only thing used for this. I can't seem to find any pre-made saddles around here and all the sheet metal shops in my area are backed up for over a week. Are there Any alternative that don't include seperating the line and adding a tee.
