Duct junction fitting

摘要

An underfloor system of ducts utilized for power and signal distribution utilizes a combination duct junction fitting which provides access to two parallel ducts while maintaining protective isolation between the ducts. The combination fitting serves to join pairs of ducts in end to end spaced apart relation, adjustably support the ducts above a base floor surface, maintain ground integrity of the system and selectively provide a duplex electrical receptacle which can be accessed from the surface and which is mounted substantially in the space between the parallel ducts. A tubular adapter is adjustable to the height of the fill above the fitting and provide for the attachment of either a closure or an above surface fitting.
