Abstract
Abstract A metal raceway structure has a metal ribbed deck cooperating with an underlying member to define a plurality of cells each adapted to carry electrical utility wires. A housing member is positioned in cooperation with the deck in such fashion that openings in the deck members will permit access to the wires in the various cells. The housing has a chamber, at least one housing electrical receptacle has a pair of electrical sockets and has a mouth disposed at the upper end thereof. At least one remote electrical receptacle has a pair of electrical sockets and is disposed above the housing chamber, has an electrical wire in electrical contact therewith and has a plug engaged within a housing electrical receptacle. The remote electrical receptacle or receptacles may be secured to a face plate which is generally horizontally oriented so as to be generally flush with an overlying floor member or may be secured to vertically oriented face plates so as to provide a tombstone construction. The housing member may have one or more housing extensions within which the housing receptacles are positioned.
