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.
