Balls are placed in strategically located holes imbedded in a strong but very thin plastic rack shaped film resulting in the tightest rack possible, with each ball touching each balls neighbor. Yet it is so thin, it does not effect the trajectory of the broken balls and is removed from the table after each break.

Make sure this fits by entering your model number.
