ABSTRACT:
A suspension ceiling grid system having grid runners connected at intersections including a through-runner and opposed runner ends connected together and to the through-runner on opposite sides of the through-runner. Each runner end is provided with an end connector which extends through an opening in the web of the through-runner. Each connector is provided with a first-end-in-lock which connects the connector to the through-runner itself and a dual connector-to-connector lock which interconnects the two connectors at the intersection. The first-end-in-lock provides opposed lateral projections which engage the remote side of the web of the through-runner beyond the ends of the opening therein. The connectors may be disassembled from an intersection without the need for tools and without damage to either the connector or the through-runner opening. Further, an intersection can be disassembled and subsequently reassembled in a trapped module condition.
