Abstract
A hook type assembly that interlocks a pair of intersecting cross-beams and a main beam in a grid for a suspended ceiling. A gapped ridge in a clip on each cross-beam engages the other gapped ridge in a vertical movement that is part of a hooking action while the assembly is formed. The assembly can be optionally made to provide for expansion during a tire.
