A support for tamper proof securing a light fixture including a housing having a peripheral mounting flange on a ceiling panel including a fixture receiving opening having spaced apart side and end margins surrounding the fixture receiving opening and having inner and outer surfaces. The support has a hanger bracket which bridges the opening at a location between the end margins. Each of a pair of spaced apart jacks adjustably mounted on the hanger bracket has an abutment which is movable into a backstop position relative to the outer surface of the respective fixture receiving opening side margin. A suspension device on the hanger bracket is connectable with the light fixture housing, after the fixture housing has been inserted through the opening, for moving the fixture into a finally installed position wherein the side margins are clamped between the mounting flange of the fixture and the abutments on the jacks. In a preferred embodiment, the abutments are separate hold-down bars which extend along the side margins of the fixture receiving opening.

The modular rail assembly of the present invention includes at least one post, at least one rail, and at least one sleeve. The post is mounted to a surface and preferably extends upward. A sleeve is inserted into openings in the post. The openings are on opposite sides of the post. The sleeve preferably has a flange that contacts the post and prevents the sleeve from sliding completely thorough the openings. A rail is slid through the sleeve and preferably extends parallel to the surface. A single rail can extend through several posts. The sleeve acts as a buffer and protects the rail finish from being scratched or damaged by the post. Because of the sleeve, the modular rail assembly can be reassembled in any position without showing scratch marks or unpainted portions of the rail. In the preferred embodiment, a cap covers the top end of the post. There is also an opening in the cap into which a sleeve is inserted.

The suspended security ceiling system includes a plurality of elongated ceiling panels having a planar web section and rail portions extending along the opposite side edges of the web section, a pair of channel-shaped wall mounts mounted on the opposed walls of a room, such as a prison or jail cell, and having an upper laterally extending flange and a lower laterally extending flange on which one end of a ceiling panel rests. The ceiling panels are held in place by channel-shaped retainer clips which are arranged to snap in between the upper and lower flanges of the wall supports at locations between the ceiling panel rails and have a lower leg which bears against the surface of the web sections of the ceiling panels to clamp them against the lower flanges of the wall supports. For larger rooms requiring ceiling panels end to end, generally inverted T-shaped intermediate supports suspended from ceiling joists or other overhead support and extending parallel to the wall supports are used. The intermediate supports resemble back to back wall supports and ceiling panels are held in place on the lower flanges of an intermediate support by retainer clips similar to those for the wall supports.
