Abstract: A utility floor box includes a body having a horizontal base, first and second longitudinally extending side walls extending from first and second opposed edges of the horizontal base, and first and second laterally extending end walls extending from third and fourth opposed edges of the horizontal base. At least one of the first and second side walls defines a branch opening, and at least one of the first and second end walls defines a duct opening. First and second horizontal support bars extend through aligned first and second support openings in the first and second side walls. First and second vertical support legs are secured to the first support bar, and third and fourth vertical support legs secured to the second support bar. The first, second, third and fourth support legs are vertically adjustable with respect to the corresponding first and second support bars.

Abstract: An housing is configured for connection to the raceway panels by removing the concrete above the raceway panel, cutting a hole in the raceway panel, and securing the housing in the hole in the raceway panel. Alignment clips allow the afterset housings to be ganged together to form an integral afterset assembly. Each alignment clip is configured to slidably engage with a pair of the afterset housings. In one embodiment, the afterset housing includes a preset housing that is normally configured for connection to the raceway panel prior to pouring of the concrete floor, and an adapter connectable to the preset housing and being constructed to reconfigure the preset for use as an afterset housing which is adapted for connection to the raceway panel following pouring of the concrete floor.

Abstract: A preset is provided for providing access at selected locations to an underfloor electrical distribution system of the type consisting of at least one raceway panel adapted to be positioned in a concrete floor. The raceway panel defines an interior passage adapted to carry service cables and has an exterior wall defining a preset opening that provides access to the interior passage. The presets can be located at any location where an opening is punched in the raceway panel, with 12 inch or 24 inch intervals being mostcommon. The preset includes a housing having an interior compartment, a concrete cap, and a knockout section. The concrete cap and the knockout section can be removed to provide access to the interior compartment of the preset housing. The knockout is positioned to align with and lockingly engage with the preset opening to secure the preset to the raceway panel during pouring of the concrete floor.

Abstract: A trench raceway providing multiple wire passages between an undersurface and an access surface. The access surface defines an access passage with opposing first and second access sides. The trench raceway includes a plurality of support pedestals, a trench pan, and an adjustable pan support.The pedestals provide support to the first and second sides of the access surface. The pedestals include an undersurface support, a floor support having a floor support portion and an access passage portion, and an adjustable central section intermediate the undersurface support and the floor support. The trench pan is adapted to be supported by the first and second access sides of the trench raceway to provide the multiple wiring passageways. The trench pan includes a pan section with a support passage intermediate a first and second flank supported by the access passage portions of the support pedestals.

Abstract: Trim piece for trench duct which can be used where the floor covering is tile or carpet. There are three outwardly extending flanges. In the tile mode, one flange is used as a tile separator and the other flanges are used respectively to support the trench cover and an edge of the floor tile. In the carpet mode, the trim is turned 180.degree. so the tile separator flange is inactive wile the other flange respectively support the edge of the floor tile and the trench cover. In the tile mode, the edge of the floor tile has vertical support so the breakage is avoided. This is attained by that the trim flange supporting the edge is in turn supported by the trench and by concrete.

Abstract: Side rail structure for trenchduct side rail has a lower section and an upper section. The lower section is thin, galvanized sheet steel and the upper section is an aluminum extrusion clamps connect the upper and lower sections so that in a full bottom trench the whole trench can be adjusted. In both full bottom and bottomless trench, the upper section can be adjusted with respect to lower section. In the full bottomless trench a friction fit holds upper and lower sections together.

Abstract: A preset access housing assembly is disclosed for use in underfloor electrical distribution systems having a plurality of raceway cells extending below the floor surface. The housing has a base wall and a sidewall extending upwardly therefrom and terminating at an open upper end. The base wall is proportioned to bridge between at least two separate raceway cells, and is formed with a separate opening adapted to connect with the interior of each associated raceway cell. A closure closes the open end of the housing and includes a hinged cover portion and a stationary cover portion. The hinged cover portion is openable to vertically expose at least one raceway cell opening and provide easy access thereto, while the stationary cover portion blocks easy access to at least one other raceway cell opening.

Abstract: An underfloor electrical distribution system is comprised of a bottomless trench duct transversely overlying a cellular subfloor deck assembly. The bottomless trench duct has spaced-apart, parallel L-shaped side rails, the vertical legs of which terminate in an inverted U-shaped channel and form the sidewalls of the trench. Preshaped void closure plates, which are attached to the side rails, transversely extend into the troughs of the cellular subfloor deck assembly to prevent the ingress of concrete into the trench duct while the concrete floor is being constructed. The preshaped void closure plates may be held in place within the inverted U-shaped channel by means of rivets fastened to the vertical leg of the side rail. Alternatively, horizontal slots in the inverted U-shaped channel may be cut to receive the void closure plates, which are frictionally held within the U-shaped channel.

Abstract: A preset access housing assembly is disclosed for use in underfloor electrical distribution systems having a plurality of raceway cells extending below the floor surface. The housing includes a base wall bridging between two raceway cells and communicating with both cells. A conical member is connected to the base wall around its periphery and converges upwardly with reducing diameter to an open end substantially adjacent to but below the floor surface. Closure means are mounted on the conical member and can be opened to provide user access to the housing. The finished cover means include a finish ring which projects outwardly along the floor surface around the open end of the housing and a flange which extends down through the opening. A cover plate is removably mounted in the finish ring. A bracket is mounted in the housing to support a duplex receptacle and is shaped to isolate a zone within the housing from the remainder of the housing.
