Abstract: An electrical fitting support device includes a housing having a cylindrical tubular wall with a first open end and a base end opposite to the first end. A base is provided at the base end of the housing, and is constituted by two base walls extending at right angles to each other from a central longitudinal plane of the housing and being adapted to fit over a protruding corner edge of two adjoining building walls. An inlet formation is joined to the base and includes a hole for receiving an electrical conductor. A number of protrusions extend from the housing at its first end and have threaded holes for receiving screws for fitting a lid over the open end. At least two spaced apart lugs are provided extending outwardly from the housing and each of the lugs has an aperture for receiving a fastening element for attachment of the housing to a protruding corner edge of two adjoining building walls.
