I dropped this in chat last night, but had to leave before I saw any answers, so I apologize if I missed an answer already.
I'm building a collar for a 7.2cf chest freezer. This freezer will be in a very hot, humid location pretty much all the time. I have 8" shanks and 2" shanks available. Is there any benefit/detriment of one over the other?
One one hand, the long shank seems like it would keep the faucets cold better, so the first few pints would pour better. OTOH, the long shanks may just be a conduit for drawing heat into the freezer and making the faucets drip constantly with condensation. Long shanks would also be less convenient when moving stuff around the freezer.
The short shanks are pretty much the opposite of the above points. Less heat intrusion, but warmer faucets. They are more out of the way for moving kegs in and out of the freezer.
So if you had a choice, what would you pick?
