I have never seen one of the existing rings out there. It was my assumption that they would taper to 22mm but then you know what making assumptions can do Possibly they were designed like that to work with a variety of tanks? The IBTpro 22 is purpose made for our 22mm tanks only, I dont have a clue as to if it will work with any other tanks or toppers but then thats not what they are for
I also put a taper in the top to match the taper on our 22mm caps so it seats down into it, lastly it is a little taller so the tank seats on the ring before making a connection then tightening a bit more you draw the cartomizer down making the connection so everything is nice and tight.
Waiting on the shop Cob, should not be much longer though.
Ladie, I would say there is a very good chance we will have them in our 10 colors by February or so. Because we have so many colors it means having to put a whole lot of these on the shelf so we have so our nickels up for a little while. Last month we had just begun to recover from the Lawyers and Accountants over our incorporation and getting our taxes in order. Then we did some serious restocking and of course put the Stainless IBTpro 22 on the big board. I am looking at January to recover once again before we commit to anything else.
That is all dependent on how things run through the store of course, it can swing wildly either way at times so it could be earlier or later based on the worlds current wants. We will certainly keep pluggin away on these things we recognize where we can bring top quality and value together for folks.
