Do they use the 1/4" or the 3/8" threads on the typical black fibreglass chimney rods at home depot? I want to order a brush. I think its quite large so I'd go for the 3/8 but I don't reallt remember (I'm at work now so I can't check).
I presume I need an 11x11" brush for a chimney that size? No need to go any larger is there?
Thanks!

given those choices, they must be NPT. And they are typically 1/4".
WHAT "that size"??? If your flue is an 11x11 then that's the size you need. If it is a 8" round, then THAT is the size you need.
Do you have any nuts or bolts you could try on for size? Taking unit to hardware store should help you find the right size thread.
