Turn off the draft beer from inside the beer cooler. This simple to install stainless steel valve will restrict the flow of beer from the keg to the beer faucet.
Simply shut off the beer and lock the cooler door to prevent unauthorized beer consumption after closing hours.
This method is much better than untapping the keg and depressurizing the beer every night.
