I have 2 keggles for sale. the tops have been cut out and a 1/2 inch stainless steel thread nipple has been welded into the keggles. I am in the Atlanta area asking $100 apiece for them. Never been used for beer making. I made 3 keggles thinking of making a system and never got around to it. Just doing smaller batches. will sell 2 of them if interested pm thanks
