Abstract:
1. A seismic clip for anchoring the end of a suspended ceiling grid member to a wall angle comprising a unitary sheet metal stamping, the clip having a central saddle section and a pair of mounting wings extending in opposite directions from a rear of the saddle section, the saddle section having a pair of spaced parallel generally planar walls, the walls and wings being symmetrical about an imaginary plane midway between the walls, the wings lying in a common plane perpendicular to the imaginary plane and each including a hook behind said plane for gripping a vertical leg of the wall angle, the saddle walls each having a top joined by an intermediate web from which the saddle walls vertically depend, the saddle walls being connected only at their tops such that an opening exists between the wings, the web spacing the saddle walls a distance whereby the saddle walls are adapted to straddle and snap over the top of an upper reinforcing bulb of the grid member to assemble the clip on the end of the grid member, the saddle walls having a pair of opposed tabs adjacent their forward ends adapted to engage the underside of the reinforcing bulb when the clip is installed on the grid member, the saddle walls including holes for receiving a screw to be driven into the reinforcing bulb of the grid member and elongated slots for a screw to be driven into a web of the grid member, a lanced tab in one of the saddle walls spaced to the rear from the opposed tab of its wall, the lanced tab being arranged to restrain the clip, when installed on the end of the grid member, from tilting excessively upwardly where, under seismic conditions the grid member slips in the saddle section outwardly off the wall angle and gravity pulls down on the grid member to clip assembly.
