ABSTRACT:
A centering arrangement for runners of a ceiling system for holding the panels supported by the runners in a desired position on the flanges of the runners, said centering arrangement comprising a bump extending from each side of the web with the bump being formed in a web of the runner immediately adjacent a cut in the runner so that the drawing of the material into the bump will not draw material from the flange or adjacent thereto. The bump is preferably a half moon or semi-circular shape so that it provides a smooth camming surface for both lateral movement of the panel along the flange as well as vertical movement towards the flange.
