Abstract: The invention is a covering for a suspended ceiling grid system. The covering is particularly suited to be retrofitable onto an installed suspended ceiling grid system. The covering is preferably a plastic cup that can be snap fit onto the main runners or cross-tees of the installed suspended ceiling grid system, and the covering includes an elongate body having an opposed flange and lip which facilitate easy assembly and disassembly from a suspended ceiling grid system. The elongate body of the covering may be planar or non-planar. The covering may also have notches defined in the flange and lip in a suitable arrangement.

Abstract: A surface mounted grid system for use in association with a substructure and for supporting an array of tile panels which comprises: (a) a plurality of main runners and cross-runners adaptable arranged normal to each other. The main runner has (i) a horizontally oriented surface and spaced, non-peripheral, longitudinal side walls depending transversely therefrom and includes a plurality of spaced openings; and (ii) a downwardly depending member terminating with a horizontally disposed flange having a longitudinal marginal edge. The cross-runners have (i) a horizontally disposed flange with a transverse marginal edge and arranged in a common plane with the flange of the main runner, and (ii) an intermediate longitudinal web extending transversely from the flange and having a longitudinal projection extending beyond the transverse marginal edge.
