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.
