Check the listing for details. Jockey in the Box -- portable mini keezer / draft system [52 qt]. Condition: New – Open box. Listed at 225.00 USD. It's like if a keezer and a jockey box had a child! No more hauling your kegs, cylinder, and jockey box to share your beer - this is a self-contained, portable, easy-to-use mini draft system that is great for sharing homebrew with friends and family! I use it all the time myself and I figured I would start selling them. It works with 2L PET pressurizable bottles with a PCO 1881 thread (standard 2L soda bottle you would buy at the store). It features a mini CO2 regulator with a built-in gauge which allows you to use your 2L bottles as both the cylinder and the kegs! You can use everything that comes with it to purge your bottles and fill them with beer (from your ball lock keg) or CO2 (from your cylinder). You can also set the dispensing pressure on the regulator. It is easy to swap in new bottles to keep the taps flowing! ** Comes with everything you see in the picture EXCEPT 2L bottles! ** All you have to do is fill the bottles with CO2 and beer using the provided equipment, screw the "kegs" into the tee pieces, connect the "cylinder" to the quick-connect, set the dispensing pressure, throw some ice in the cooler and enjoy some homebrew on draft! This can also be used as a normal jockey box by drilling small holes in the back and running your beer lines to the side port on the tee. When beer is pulled from the cold bottle, it is replaced by beer from the keg. I will be happy to answer any questions about filling, dispensing, swapping, cleaning, or anything else you are wondering about.
