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. The divider is pivotally mounted within the access housing. Additionally, a face plate and pivotable cover lid assembly is provided which is received within a recess in the trim ring.
