Abstract
The invention relates to a sign hanger A, for facilitating the hanging of items such as a banner or the like from suspended ceiling grids in a store. The sign hanger is adapted to have a twist-lock releasable connection with a ceiling grid. A friction lock structure 42, 58 is added to decrease the likelihood of accidental deinstallation of the sign hanger A. In one embodiment the hanger has an elongated body 10 having spaced apart flanges 125, 130 in order to hold a banner 200. In another embodiment the hanger has a centrally located plateau 864, which co-operates with tapered surfaces 836 and 850 on respective clips 804 and 808 to hold the hanger in place on the ceiling grid.
