ABSTRACT:
A gridwork for a suspended ceiling is assembled by a clip having three equally angularly disposed prongs which run parallel to three equally angularly disposed elongated rigid members of the gridwork. One prong has a stepped configuration, where each level abuts against a portion of two of the three intersecting members. One level of this stepped configuration widens into a lip fitting into a flanged or a "u" shaped channel area of one of the members, and which widened area further snaps into this one member for its securement therein. The remaining two prongs of the clip are bolted to its corresponding elongated member.
