ABSTRACT:
A separate connector piece for use in constructing a suspended ceiling grid system is provided. The grid system is of the type consisting of a series of parallel longitudinal beams interconnected with a series of perpendicular cross runners. The connector piece is selectively attached to the ends of the cross runners, and forms the interconnections when the cross runners are aligned on opposite sides of a longitudinal beam. The connector pieces of the opposing cross runners extend through a slot located in the longitudinal beam and may be attached to the opposing cross runner, thus forming the interconnection.
