ABSTRACT:
Joint clips of the invention are used in grids for suspended ceilings, at selected intersections, to create separate areas of ceiling that move independently of one another during an earthquake, to prevent a buildup of momentum in the entire ceiling. In one embodiment disclosed herein, the clips extend laterally of a selected main beam, and are formed of a pair of loosely connected identical segments that are slidably secured to a selected main beam by a cut-out in the segments. The clip extends laterally across a selected main beam and slidably receives the end of a cross beam in a pocket of the clip that extends laterally on each side of the selected main beam.
