  • Stab-in connector with expansion relief
    Publication number: 20050166523
    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.

  • Perimeter clip for seismic ceilings
    Publication number: 20050160696
    Abstract: A perimeter clip attached to a wall molding that supports a beam in a suspended ceiling intended to survive seismic disturbances. The clip is capable, during an earthquake, of permitting an end of a beam at one end of a connected line of beams, in a grid, to slide while being supported in the clip, or, in the alternative, to secure an end of a beam to the wall molding.

  • Interlocking cross tee
    Patent number: 4912894
    Abstract: A fire-resistant suspended ceiling grid structure having cross tees interlocked to main beams, to support ceiling tiles. The structure has shear means to permit a cross tee to expand into a main beam during a fire. The interlock includes tongues held in an abutting relationship by open belt loops. The tongues slide to permit the cross tees to expand longitudinally during a fire.
