These genuine pool balls are individually prepared to mount directly on your beer faucet's thread as a tap handle. Each ball is full size and weight – 2.25 inches and 6oz. These balls provide an attractive and interesting beer tap handle for your home kegerator or portable set up. Each color or number on the tap handle can differentiate the different brews you offer on tap. They give a satisfying weight and feel to the beer tap's operation and I have even been told the extra weight on the faucet's back angled shut position has stopped some annoying drips. I've done my best to photograph the balls in their correct color and photos have not been touched up at all. Choose the number on your Pool Ball Tap Handle by customizing your order- no extra charge. They make the perfect gift for the home brew enthusiast or pool player!
