An adjustable mounting lug for an electrical box that diminishes the degree of play of the adjustable mounting lug relative to at least an orientation of a front face of the electrical box. Sidewalls of the adjustable mounting lug can include a first portion comprising a first segment, and a second portion comprising a first inclined side, an intermediate curved side, and a second inclined side. The second portion can be configured accommodate the adjustable mounting lug having a relatively large height while maintaining at least a minimum length of a bottom wall of the adjustable mounting lug that is supported by a support louvre of the electrical box. The second portion also provides the sidewalls of the larger adjustable mounting lug with a configuration that can prevent the adjustable mounting lug from interfering with at least fittings in the box that can be associated with relatively large knockout openings.

A hold-down clamp for holding a cable tray on a strut channel includes a main body member extending between first and second ends, opposed side walls extending downwardly and perpendicularly from the main body member, and first and second side members extending from each of the opposed side walls. The main body member has a first end defining a clamp engagement portion and a second end defining an expansion guide portion. Each of the first and second side members includes a flange having a clamp engagement structure, a planar middle structure, and an expansion guide structure that are integrally connected to each other, and a clamping tooth, which is defined between the clamp engagement structure of the flange and the side wall such that the clamping tooth transitions into the clamp engagement structure of the flange and the side wall of the hold-down clamp.

An electrical outlet box extension comprising a perimetrical side wall with an inner surface and an outer surface having an open front face and an open rear face and defining an interior space, and having at least one outwardly protruding resilient tab located on the side wall outer surface. The box extension is designed for adjustable insertable receipt within an electrical outlet box for increasing the depth of the box.

Pull out extension contained in electrical box

An electrical outlet box for accommodating an electrical fixture which includes a generally rectangular box having a back wall, a perimetrical side wall surrounding said back wall defining an open front face and a box interior, said side wall includes a first and second set of generally parallel spaced apart wall portions; and a slidable extension nested within said generally rectangular box, that can be moved from within the generally rectangular box to an extended position beyond the open front face.

Electrical box for concrete walls

An electrical outlet box for accommodating an electrical fixture includes a generally rectangular box having a back wall, a perimetrical side wall surrounding said back wall defining an open front face and a box interior, said side wall includes of a first and second set of generally parallel spaced apart wall portions; and a slidable extension nested within said generally rectangular box, that can be moved from within the generally rectangular box to an extended position beyond the open front face.

The present invention is directed to a method of manufacturing an electrical box to reduce the amount of scrap material therefrom. More particularly, the present invention provides a metallic electrical outlet box that is formed from a sheet of material and folded into an electrical box.

Method for manufacturing electrical boxes

Tubular member clamp

An electrical box for supporting sheathed electrical cables therein holds and supports electrical cables in a preferred arrangement. A cable clamp structure is used for clamping electrical cables to a surface of an electrical box. The cable clamp structure has an arched configuration and serrations on a cable contacting surface in order to more efficiently store electrical cables in an electrical box.
