ABSTRACT:
A service column comprising a pair of channels in a main member for receiving electrical conductors providing power and communication services from above a suspended ceiling to a work area in an office. The suspended ceiling contains inverted T-rails supporting a plurality of ceiling panels. An adapter bracket assembly fastened to the upper end of the main member of the service column secures the main member to one of the inverted T-rails. The inverted T-rail supporting the service column is defined by two split legs joined together by a web. The adapter bracket assembly abuts against the web and a double C-clamp secured to the adapter bracket assembly with a fastener grippingly engages the split legs of the inverted T-rail. A standard secured to the lower end of the main member of the service column adjustably supports the column from the floor and a sleeve slideable over the main member conceals the standard from external view.
