Abstract

An upright electrical power and telecommunication distribution having a plurality of upright posts disposed in horizontally spaced relationship, and horizontally-elongate rails extending between and rigidly joined to each adjacent pair of posts. The lower rail defines a channel for accommodating electrical power cabling, and the upper rail also has a channel for accommodating communication cabling. The posts define openings therein to enable the power and communication cables to pass through the post for communication with the rails which are joined thereto. The upper rail is open on the top and accommodates a removable cap to facilitate laying in of telecommunication cables, and one of the side walls of the upper rail has openings for accommodating boxes or plates mounting telecommunication connectors. The lower rail is open on the bottom to facilitate insertion of electrical power cabling, the bottom being closed by a removable cover. In the preferred embodiment electrical power is provided by a power module including a power block which attaches to and is suspended from the underside of the lower rail, which power block accommodates a removable receptacle unit on either or both sides thereof. The power module has an elongate cable projecting the power block and which extends longitudinally along the lower rail for projection into an adjacent rail, with the cable having a pluglike connector which can be engaged with a power block mounted on the adjacent rail.
