Abstract: An electrical service fitting apparatus includes a base frame having a frame opening defined therethrough. An extensible service fitting is disposed through the frame opening and movable relative to the base frame between a retracted position and an extended position. The base frame has a plurality of grooves defined therein which open into the frame opening. The service fitting has a plurality of elongated ribs defined thereon which are received in the grooves so that the ribs may slide in the grooves to guide the service fitting as it moves between its retracted and extended position. A pair of coiled tape springs are connected between the base frame and the service fitting to bias the service fitting toward its extended position. Two sliding latches are provided to lock the service fitting in its retracted position. A top plate of the service fitting has access openings defined therein through which attachment devices can be accessed so as to mount the apparatus on a duct placed in a concrete floor.

Abstract: An electrical duct system is provided having a flush floor fitting associated with a multi-cell duct placed in the floor. A top wall of the duct has a central access opening and two outer access openings communicated with a central cell and two outer cells of the duct. An access housing is located in top of the duct. A trim ring on top of the access housing has first, second and third mounting spaces for mounting outlet devices therein. A divider is located in the housing and divides the interior of the housing into first, second and third chambers associated with the first, second and third mounting spaces of the trim ring. The first and third chambers overlie and are communicated with the central access opening of the duct. The second chamber extends between the first and third chambers and is communicated with both of the outer access openings of the duct and is isolated from the central access opening. The divider is telescopingly extendable to accommodate different heights of access housings.

Abstract: A monument fitting for use with an electrical raceway system to be placed in a floor provides for alternative selection of top or side access. The monument fitting provides openings permitting either top or side access, and an electrical outlet placed in the openings can be relocated after the monument fitting has been placed in service.

Abstract: A preset insert construction is provided for a raceway system designed for placement in a concrete floor. A duct has an access opening defined in a top wall thereof. The access opening has a primary perimeter and a plurality of notches extending beyond the primary perimeter. A preset insert has an extension collar defining an insert opening therethrough similar in size and shape to the access opening. A support flange extends outwardly from a lower end of the collar. A plurality of locking tabs extend downward from the collar below the support flange. Each locking tab includes an outwardly extending locking lip portion. The locking tabs are located relative to each other in a pattern corresponding to the notches of the access opening, and are located on the preset insert so that when the tabs are initially inserted into the notches, the insert opening is partially out of alignment with the access opening.
