How to connect a beer tower to a ball lock keg?

Beer towers come standard with beer nuts. Beer nuts will connect to most professional beer couplers and are easily interchangeable. Ball locks on the other hand are a different type of beer coupler. The standard beer nut connection will have to be removed and replaced with a black ball lock coupler.

Black ball lock couplers are for the beverage side of a Corny keg, while the white/grey ball lock is for the gas side. They are slightly different and need to be connected to the proper post on your Corny keg.
