A ceiling system including: a ceiling structure suspended in an interior space. The ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.

Components for a suspended ceiling subjected to seismic events including a fixed bracket and a movable bracket presenting a contiguous flat ceiling surface under normal conditions. The movable bracket is able to slide up onto the fixed bracket during a seismic event and is returned to a neutral position with the aid of a sliding clip elastically attached to a main tee or cross runner of the ceiling. A clip for joining tee members of a suspended ceiling is provided comprising two joined arms with hooks at the end of each arm. The join of the arms sits atop a main tee member and the hooks of each arm engage cross members thus securing the members together.

A roll formed sheet metal main runner and a roll formed sheet metal cross runner intersecting the main runner from one side at a slot in the main runner, the cross runner having a sheet metal end connector extending through the slot, the connector having a lateral projection with a rearwardly facing edge and a hole rearward of the projection at which the connector is fixed to the cross runner, a stamped sheet metal anchor clip with a tongue projecting through the slot and a base connected to the tongue on a side of the main runner opposite the cross runner, the tongue having a relief area aligned with the connector projection, an edge abutting the connector projecting edge, and a hole aligned with the connector hole, and a fastener through both of said connector and tongue holes securing said clip to said connector.

An adapter for securing a cross beam to a main beam in a suspended ceiling. The adapter includes a first leg having a ramp portion on a top edge of the first leg and a hook portion on a bottom edge of the first leg, a second leg attached to the first leg on a first side of the first leg. The second leg includes a larger portion which extends above the first leg to a second side of the first leg.
