Electrical boxes and fittings are foundational components in any commercial, industrial, or residential wiring installation. The box provides the structural housing for wiring connections and device mounting, while fittings secure conduit runs and manage cable entry points. Selecting the right box type for the application is critical for code compliance, installation efficiency, and long-term reliability.

Metallic boxes in square, round, octagonal, and masonry configurations are the standard choice for commercial and industrial work, where conduit systems and larger conductors are the norm. Square boxes are the most versatile format, used throughout commercial conduit systems as device, junction, and pull boxes. Round and octagonal boxes handle ceiling outlet and fixture mounting applications. Masonry boxes serve concrete block, brick, and poured concrete wall assemblies where no stud cavity exists.

Plastic boxes are widely used in residential and light commercial new construction where nonmetallic sheathed cable is the primary wiring method. Their lightweight construction and integrated cable clamp designs speed up rough-in in typical stud-wall applications.

Weatherproof boxes and in-use covers are required for any outdoor or damp-location installation, from exterior receptacles on commercial buildings to parking lot and landscape device locations. Floor boxes bring power and data access to open office floor plates without exposed conduit runs.

Ceiling fan support boxes provide the rated mounting structure required wherever a fan is installed. Panel and breaker accessories, and raceway support hardware round out this category for commercial electrical projects from rough-in through finish.
