DUAL PRESET SERVICE FITTING OR INSERT FOR UNDERFLOOR WIREWAY SYSTEMS ABSTRACT OF THE DISCLOSURE The fitting is mountable on a cellular steel floor or deck prior to pouring of the concrete of a completed floor and comprises a separable flat base plate, a box-like housing, and a cover plate. Two self-grommeted openings in the base plate are axially aligned with respective openings of substantially equal size leading to adjacent cells of the deck, and a tab on the base plate at one of the grommeted openings interlocks with the deck to hold the base plate in position. Horizontally directed slots formed in the base. plate along one longitudinal edge thereof cooperate selectively with tabs on the lower longitudinal edges of the housing to lock the housing on the base plate selectively in either of two positions. Screws or rivets may be used as additional fastening means for the base plate and housing. A longitudinally asymmetrical opening in an upper wall of the housing is closed by a filler cap prior to pouring the concrete and, after the pour, the filler cap is removed to permit the cover plate, also termed a flush floor fitting, to be installed over the opening in the upper wall. A closure member of the cover plate is turnable to expose openings for wires leading from the housing of the service fitting.
