RACO 190 two-gang square box

The RACO 190 is a UL-listed square electrical box with a 21 cu in capacity and two gangs for devices. It is made of galvanized steel with a gray finish and measures 1-1/2 in deep by 4 in wide and long. The box suits new residential or commercial wiring where a standard square box is required.

Compatibility checks before ordering

Verify that a 21 cu in volume satisfies the conductor-fill rules for the circuit you are wiring. Confirm the 1-1/2 in depth fits the wall or ceiling cavity you are working in. Ensure the four 1/2 in. back knockouts and twelve 1/2 in. side knockouts match your conduit or cable entry plan. The box has no integral clamps or brackets, so separate mounting hardware and cable connectors are needed.

Behavior under sustained load

The galvanized steel construction resists corrosion during long-term exposure in damp or outdoor locations. UL listing confirms the box meets safety standards for continuous use at rated capacity. Steel walls maintain rigidity when multiple devices are mounted and conductors are pulled through the knockouts over time. No plastic parts are present to degrade from heat generated by sustained current flow.

Questions about this item

What comes with the RACO 190 box and what must I purchase separately?

The box is sold as a single steel unit with 12 side knockouts and four back knockouts. Covers, cable clamps, mounting screws and conduit fittings are not included and must be bought separately.

How do I know the 21 cu in capacity is the right size for my wiring job?

The 21 cubic-inch volume is the maximum conductor fill allowed by code for this two-gang square box. Count every insulated wire, device yoke and grounding conductor in your circuit; if the total fill stays at or below 21 cu in, the box is suitable.

What does the UL Listed marking on the RACO 190 mean once the box is installed?

UL Listed confirms the steel enclosure meets the safety construction and performance requirements of the applicable UL standard, so it is accepted by electrical inspectors for use in residential and commercial wiring systems.
