Abstract
Abstract An underfloor access housing adapted for use with electrical raceway sections of the type normally placed in building floors. The access housing spans across adjoining raceways and is provided with inlet openings, each communicating with one of the adjoining raceways, and a central dual outlet opening providing communication between the interior of the housing and the space above the floor level. A partition detachably retained within the housing, divides the interior of the housing into separate compartments, each including one of the inlet openings. The partition is adapted to support an electrical plug receptacle whereby electrical connections may be made beneath the level of the finished floor.
