This 4 in octagon steel box is used for mounting ceiling or wall lighting fixtures in conduit wiring systems. Its 2-1/8 in (54 mm) deep body provides 21 cu in (approximately 344 cm³) of box capacity for fixture leads and branch-circuit conductors.
Use for luminaires, wall lights, and other fixture points where a metallic octagon box is required. Commonly selected for commercial, institutional, and residential jobs using conduit and standard 4 in octagon covers or fixture canopies.
Avoid using this box where nonmetallic cable clamps are required, where a device box is needed for switches or receptacles, or where box fill calculations exceed the listed 21 cu in capacity. Always confirm conductor count, fitting size, and local code requirements before installation.
Best for electricians needing a CSA listed steel octagon box with concentric 1/2 in and 3/4 in knockouts for conduit runs. The deeper profile helps when fixture wiring space is tighter than a shallow octagon box allows.
Typically installed in ceilings and walls in commercial and residential construction across Canada, especially where EMT or other conduit systems are used. Suitable for exposed or concealed raceway installations where a metallic fixture box is specified.
This box provides a standard 4 in octagon mounting point for lighting fixtures while maintaining metallic continuity in conduit systems. The added depth increases wiring space compared with shallower octagon boxes, which can help on fixture rough-in and final terminations.
Compared with shallow octagon boxes, this 2-1/8 in (54 mm) deep version offers more internal volume for conductors and fixture leads. Compared with nonmetallic fixture boxes, it is intended for steel conduit-based installations and includes concentric 1/2 in and 3/4 in knockouts plus a raised ground screw.
