ABSTRACT:
An electrical junction box has internal mechanics allowing at least one receptacle to be pulled out as an extension cord. The cord unwinds and rewinds on a spool inside the junction box. A return spring and a releasable ratchet allows the cord to be stopped by the user at various lengths either when pulling the receptacle from the junction box or returning it to the box. The junction box can be use in residential homes, commercial buildings, offices, school rooms, and other structures as a standard 110 volt electrical outlet and self-contained extension cord.
