I have 18.5 inches in my freezer from my hump to top. If I use a 1" X 8" collar, I should have around 26.5 inches. A soda keg is 23 inches. Is that enough room? Trying to keep collar small because I will attach it to freezer and only hing the lid. Another question, as far as a drip tray is concerned - I saw a three hole drip tray. Does this kind get mounted to the faucets for support? Is that a good or bad idea? Thanks in advance. Getting ready to go all grain and keezer !!!!
