I'm having trouble figuring out how long I need my shanks. I'm planning on making my collar 2" thick and then I'm putting a facade in front of my keezer to blend in with the cabinets that I'm thinking should add another 2" max. When reading the desciption of the shanks at beveragefactory, they said that "This shank is 5-1/8" long measured from the end of the threading to the end where the faucet attaches". So what I guess I want to know is how much space do I have from the flange on the outside to the compression ring that secures it. I can make guestimates but I don't want to have to return my shanks for being too short or have a lot of extra shank length getting in the way either.
