A torsion spring ceiling grill that is reconfigurable to adapt smoothly to various thicknesses of ceiling tiles. The ceiling tile has an opening to which a grill plate and a backing plate correspond. The grill plate attaches to the backing plate via the torsion springs, clamping the ceiling tile in between. The torsion spring assemblies can be reconfigured by repositioning an axle of each torsion spring assembly in its respective slot in vertical spring support panels of the grill plate. The torsion spring assemblies can be releasably secured at any position along the slot. The backing plate has spring-receiving openings on a top horizontal panel that extends out over the opening in the ceiling tile to receive arms of the torsion springs. Arms of the torsion springs may be bound by a severable connector which is severed by a blade above the top horizontal panel during installation.

A small speaker for panel mounting in a hole as small as seventy five millimeters diameter in which access to the rear of the panel is not required. The small speaker uses spring-loaded flip dogs that are actuated by rotating a sound disperser that is connected to a hollow cylindrical mechanism having gear teeth on its external surface which engage flip dog gears on the top surfaces of the flip dogs. Internally, the hollow cylindrical mechanism has an indentation that supports a speaker baffle which, in turn supports a speaker bushing. A loudspeaker is attached to the speaker bushing near the speaker baffle. Two housing sections attach, spaced apart, to an annular frame on opposing sides and receive the hollow cylindrical mechanism rotationally therein. The flip dogs operate in the spaces between the housing sections. Methods of mounting and dismounting are described.

A half-rack electronics cabinet coupled to a wall mount by two doubly-nested four bar mechanisms that are operable to articulate the cabinet by ninety degrees to bring the back planes of any installed electronic modules to the top for easy access. The function of admitting outside signal and power cables is apportioned to the wall mount. The unit is compact, as the wall mount is no wider than the cabinet. For a half-rack cabinet of sufficient height, crossbars are provided that enable vertical mounting of full-rack electronic modules in the half-rack cabinet along with, preferably, at least one half-rack module.

Crossbars span the width between two opposed vertical attachment bars in a half-width electronics rack or cabinet of accommodating height to enable vertical mounting of full-width electronics module in the half-width electronics rack or cabinet. The crossbars are used in opposed spaced-apart pairs with the full-width electronics module mounted vertically between the crossbars. Each crossbar includes a flat elongated main bar having five sets of three holes in a linear array, with the holes sized and spaced apart in accordance with industry standards for electronics racks. An attachment flange with a fastener opening extends from each end of the main bar and is delineated from the main bar by a notch. Between the notches, the same edge extends in a right-angle bend which further extends into a flange. Crossbars are provided in pairs, with or without packaging, racks, cabinets, and electronics modules.
