Electrical Box for Two-Gang Installations

The Hubbell RACO 167 is a 21.5 cu in octagon electrical box designed for two-gang device mounting in residential or commercial wiring projects. Its galvanized steel construction provides corrosion resistance for long-term durability in dry or damp locations. UL Listed compliance confirms it meets recognized safety standards for electrical enclosures.

Knockout Layout and Mounting Flexibility

The box features three 1/2 in. and two 3/4 in. back knockouts plus two 1/2 in. and two 3/4 in. side knockouts, allowing multiple conduit entry options without additional drilling. A nominal depth of 2 1/8 in. and 4 in. square footprint fit standard framing cavities while providing ample wire-bending space. No integral clamps or brackets are included, so installers supply their preferred mounting hardware and cable connectors.

Suited for Standard Two-Gang Wiring Jobs

This unit suits electricians and DIYers running two switches, receptacles or a combination device in a single octagon box where 21.5 cu in. capacity satisfies box-fill requirements. Projects needing a deeper box, built-in cable clamps, a mounting bracket or a non-metallic enclosure should consider alternative models.

Questions about this item

How many cubic inches of wiring space does the 21.5 cu in octagon box provide for a two-gang installation?

The box is rated at 21.5 cubic inches of capacity, which is the maximum conductor volume allowed by code for this two-gang octagon enclosure.

What is the steady-state temperature rise of the galvanized steel box when circuits are loaded continuously?

The galvanized steel enclosure dissipates heat passively; its temperature rise depends on the actual conductor load and ambient conditions rather than a fixed rating.

Which mounting brackets or straps must I already have to secure this 4-inch by 4-inch octagon box?

No bracket is included — the box has standard 1/2-inch and 3/4-inch knockouts for direct conduit or cable connector attachment to the structure.
