Predator Arcos II Magnetic Cue Ball for Pool with Green Logo Predator is unleashing an all-new, wickedly accurate, and highly durable white magnetic billiard cue ball for coin-operated pool tables that work with a magnet system to separate the cue ball from the other balls. This ball has the magnetic material spread evenly around the entire ball to give it the truest roll and maximum performance. Its diameter is also the standard 2 1/4" or 57.2 mm diameter, which makes it the same size as standard pool ball sets. It is much more enjoyable to play than smaller-diameter cue balls. Compatible with the Apex 7ft Coin-op pool table and many more. The Predator magnetic cue ball features our own highly guarded, secret twist on the original phenolic formula John Wesley Hyatt first introduced to billiard balls way back in 1865. Our goal, as always, is to help you elevate your play by applying the highest standards of performance and technology to the tools of the game. Weight: 165g Diameter: 2.25in (standard diameter for a pool cues ball)
