Abstract

An electrically operated heater fan is suspended by a bracket from a building wall using a bracket mount having a plug lock which is releasably lockable within one of a pair of plug receptacles of a standard wall outlet with the plug of the heater fan fitting into the other plug receptacle. The plug lock of the bracket mount comprises a pair of electrically insulated flat slot fitting prongs and an electrically insulated ground opening fitting post which is adjustable between a receptacle insertion position and a receptacle locked in position by a control member rotatable on the bracket mount.
