A ceiling grid strut is provided that includes a rail and a strut channel that is integral to the rail. A ceiling grid assembly is provided that includes a first ceiling grid strut, a second ceiling grid strut, a first threaded fastener, a second threaded fastener, and a connector.

Described herein is a spring clip for mounting ceiling panels equipped with torsion springs to a ceiling support grid. The spring clip includes a body including a mounting portion defining a downwardly open receptacle configured for receiving a portion of a ceiling grid support member of the ceiling support grid, the downwardly open receptacle extending along a receptacle axis from a first side open end to a second side open end; and a pair of lateral flanges extending transversely outwards from the mounting portion and terminating in lateral edges, at least one of the flanges includes a slot extending parallel to the receptacle axis and configured to receive arms of a torsion spring, and a lateral opening extending from the lateral edge to the slot to allow lateral insertion of the arms of the torsion spring into the slot.

A ceiling system which includes a substrate and securing members configured to engage a grid system to mount the substrate to the grid system. The securing members may include a mounting flange positioned with its bottom surface adjacent to the substrate. The mounting flange may be coupled to the substrate via fasteners. The securing members may further include a positioning member protruding from a top surface of the mounting flange and terminating in a distal edge. The positioning member may have a first side edge and a second side edge. The securing members may include a grid engagement member extending from the distal edge of the positioning member. The grid engagement member may be located centrally between the first and second side edges of the positioning member. The grid engagement member may have a U-shaped engagement portion configured to engage a grid member of the grid system.
