Abstract: A pool rack assembly for arranging a plurality of pool balls into an operative orientation upon a pool table comprises a containment assembly. The containment assembly includes a first containment member disposed in pivotal relation with a second containment member via a pivoting interconnection. The pool rack assembly is pivoted into a closed disposition to facilitate arrangement of the plurality of pool balls into the operative orientation therein, and pivoted into an open disposition for removing the pool rack assembly from the operatively oriented pool balls. An alignment module may be removably connected to the containment module, and includes at least one light source which projects one or more light indicators. The light indicators are used to align the pool rack assembly, and more importantly, the plurality of operatively oriented pool balls therein, upon a pool table with reference to the rail markers.
