load capacity of the ceiling grid another constraint on a manufacturer is the need to use the same end connector configuration for any cross tee 12 regardless of the duty rating of the grid the requisite variation in the web thickness of conventional tees and the need for a single end connector or clip configuration has been problematic if the connector is proportioned to fit thick webs slotted grid tees with thin webs are loosely held by the connectors if a connector would be proportioned to fit closely with a conventional slotted tee with a thin wall web it would not lock with a mating identical connector on a heavy wall slotted tee because the thicker web would hold the connectors apart the invention solves the problem of a loose fitting slotted tee by locally modifying the grid tees in the web area of the slot so that regardless of the gauge thickness of the material of their web they present the same or nearly the same effective thickness to the connectors preferably according to the invention this is done by permanently displacing material adjacent a slot so that the plane of a surface of the displaced area abutted by a connector has the same or nearly the same spacing from the center of the web as corresponding areas adjacent the slots of grid tees with webs of other thickness more specifically web material is permanently displaced by a stamping operation to form an indentation 26 a surface 27 of a base of the indentation 26 has a predetermined distance d fig5 from a center plane 29.
