Abstract
A V-shaped indent is formed in a stab-in connector for a suspended ceiling grid. The indent forms a vertical bend line. In a fire, the connector bends along the vertical bend line to permit a cross beam in the grid to expand while keeping the grid intact, and thus capable of continuing to support the panels.
