  • Patent number: 6523314
    Abstract: A grid tee for a suspended ceiling system having integral centering tabs to prevent misalignment of the tee in the space between adjacent ceiling tiles that could otherwise allow the edge of a tile to slip off a flange of the tee. The centering tabs are cut out of the web of the tee with a cantilevered free length that is sufficient to enable the tabs to deflect a relatively large fraction of the width of a flange portion without permanently bending whereby variations in the widths of tiles are accommodated without development of excessive forces which could otherwise cause the tabs to impale themselves into the edges of the tiles.
