1.6 RACKING THE BALLS (8-BALL RULE)

The object balls (1-ball through 15-ball) are to be racked as tightly as possible in a triangular shape, with any strip or solid at the apex of the triangle and on the foot spot, the 8-ball in the middle of the triangle, a striped ball in one corner of the rack and a solid ball in the other corner. The base of the rack should be parallel to the foot cushion.

If, after the balls have been racked, all balls in the rack are not in contact with one another, also known as a "loose rack", the shooter who is to break may request a re-rack. At which time the opposing shooter is to re-rack the balls so that all balls in the rack are properly contacting one another, also known as a "tight rack".
