Abstract: There is a disclosure of a system for a wall mounted electrical duplex outlet receptacle that can be removed from the wall and includes a length of electrical extension cord integrally attached to provide electrical power to distant locations. When the duplex assembly is installed and latched to an interior box in the wall, the redundant length of the extension cord can be removed out of the interior box and wound about a spring loaded roller reel located remotely away from the box and duplex through the interior of the wall providing for the availability of a substantial length of extension cord when the duplex is to be removed. When installed in the wall, the duplex appears similar to a standard electrical duplex with a standard face plate. In addition, the invention includes structure for latching the duplex to the wall in the interior box as well as for an improved electrical connection between the roller reel and the outside electricity source that eliminates twisting of the wire as the reel rotates.
