Abstract
A locking connection fastens two oppositely positioned cross runners perpendicular to another runner. Compressible tabs on the cross runners are inserted in slots of the other runner to fasten the three runners together. The tabs at one connection are positioned one above the other and the tab on one cross runner projects into a cutout of the opposite cross runner. Two cutouts on the opposite sides of each tab lock the runners together.
