Abstract: A bracket assembly is disclosed, which is useful with a combination of an electrical box, a plaster ring, and a fastener or fasteners for fastening the plaster ring to the electrical box, for mounting the combination between two building studs, which are spaced within a range of spacings. The bracket assembly comprises a first bracket and a second bracket, each bracket having a mounting base, which is adapted for mounting to one of the building studs, and each bracket having two parallel legs, which extend from the mounting base of said bracket. At least part of each of the parallel legs of the first bracket is adapted to lie over or under and to slide along at least part of one of the parallel legs of the second bracket, in a telescoping relationship, when the bracket assembly is mounted so that the mounting bases of the brackets are mounted to the building studs, whereby the first and second brackets can be slidably adjusted to accommodate any spacing of the building studs within a range of spacings.

Abstract: For an electrical box having a plaster ring, which has a projecting portion defining a generally rectangular aperture, a protective cover having a front panel and flanges is mountable so as at least substantially to cover the generally rectangular aperture. A top flange has two lateral portions, each spaced by a slit from an upper edge of a lateral flange. A bottom flange has two lateral portions, each spaced by a slit from a lower edge of a lateral flange. Each lateral flange has an outer surface that is planar except for a recess adapted to receive a tool inserted between such lateral flange and an adjacent edge of the generally rectangular aperture.

Abstract: As stamped from sheet metal, an elongate hanger for hanging an electrical box between a pair of ceiling panel-supporting bars has two opposite ends, a main panel with a front surface and a back surface, a lower flange, and an upper flange. Each flange projects from the front surface and has plural grooves. Each groove is arranged to receive a tire wire wrapped around the hanger so that the tie wire is restrained in that groove against slipping along the hanger. At each of the opposite ends, the main panel has a pair of slits defining a tab adopted to be bent at a right angle. Each tab has a hole arranged to receive a fastener to fasten the tab to a ceiling panel-supporting bar extending at a right angle to the hanger.

Abstract: As stamped from sheet metal, a hanger useful for hanging an electrical fixture from a suspended ceiling has a main panel, a lower flange, and an upper flange. Near each of its opposite ends, the hanger is provided with a slot defining a tab. The slot opens at and the tab extends to a projecting edge of the lower flange. Corners defined where the projecting edge of each of the upper and lower flanges meets each of the opposite ends of the hanger and where the slot opens at the projecting edge of the lower flange are rounded approximately to a radius not less than approximately 1/16 inch. Because of the rounded corners, an installer can handle the hanger and can manipulate the tabs with bare hands, without exposure to sharp corners at the corners so defined and so rounded. The slots are spaced equally from the opposite ends of the hanger.

Abstract: An elongated conduit support to suspend a plurality of conduits from an overhead structure includes a generally flat, elongated central plate having with a plurality of closed-perimeter conduit holes to receive conduits therethrough. The elongated plate has strengthening flanges extending along its longitudinal edges of the central plate to prevent buckling of the central plate due to the weight of the conduits and suspension-receiving means including at least first and second passageways, each of which is generally parallel to the central plate and close to the plane of the central plate and perpendicular to the longitudinal side edges to hold the plate so that its plane is substantially vertical and to transfer the weight of the conduit support and the conduits thereon to the suspension means.
