Wiremold 2-Gang Switch/Outlet Box B32

The Wiremold B32 gives you 1-3/8 inches of depth in a 2-gang metal box — exactly what you need when standard boxes can’t handle bulky devices. Contractors use it for mounting dimmer switches, GFCIs, and fan speed controls without the cramped wiring that leads to callbacks.

Skip it if you’re cutting into drywall anyway. This box costs more than a standard electrical box and only makes sense for surface-mount applications where you need to preserve existing walls.

The Extra Depth That Matters

That 1-3/8 inch depth provides ample space for wiring and bulky devices — critical when you’re dealing with modern dimmers that eat up box space. At 4-3/4 inches square, the footprint stays reasonable while giving you room to work.

The depth advantage shows up most with GFCI outlets. Standard boxes force you to cram the GFCI’s bulky internals against the back, risking wire damage and making future service a nightmare. The B32’s extra space lets wires sit naturally behind the device.

Surface-Mount Design for Real Applications

Surface-mount design eliminates the need to cut into walls — the entire point of choosing Wiremold over standard boxes. Designed for use with Wiremold 500 and 700 Series Metal Raceway systems, the B32 becomes part of a complete surface wiring solution.

No knockouts means you’re committed to the raceway approach. The box accepts wiring only through the designated raceway entry points. This keeps the installation clean but limits flexibility if you need to add a circuit from a different direction later.

Rugged steel construction beats plastic boxes when mounting to concrete block or metal buildings. The neutral ivory finish works in most commercial settings, though it shows dirt faster than white.

Performance in the Field

Users rate the B32 at 4.6 out of 5 stars, with 69% giving it full marks. That’s solid performance for an electrical box — contractors don’t hand out 5-star ratings for products that cause callbacks.

Some noted that the mounting screws for receptacles can be slightly difficult to start due to the powder coating in the threads. Chase the threads with a tap or the device screws themselves before final installation. Minor annoyance, but worth knowing before you’re on a ladder.

Installation follows standard Wiremold procedure: mount the base, connect raceways, install devices, then snap on the cover with four screws. The powder coating may occasionally obstruct screw threads — same issue shows up during device mounting.

Comparing Similar Options

Wiremold offers the B31 as a single-gang version when you don’t need dual devices. The V5747-2 Professional-series provides the same 1-3/8” depth in their higher-end line. Need more room? The V5744S-2 jumps to 2-1/4” depth for seriously bulky installations.

The V5751-2 starter box includes knockouts for transitioning from existing flush boxes — useful when extending from standard wiring to surface raceway.

Warranty Coverage

Legrand Wiremold backs the B32 with a standard limited warranty for one year from installation or two years from purchase, whichever comes first. Standard coverage for commercial electrical components.

FAQ

What makes the B32 different from a standard 2-gang box? The 1-3/8 inch depth provides extra room for bulky devices, and the surface-mount design means no wall cutting. It’s specifically designed for Wiremold raceway systems, not standard in-wall wiring.

Can this box handle regular Romex wiring? No. The B32 has no knockouts and only accepts wiring through Wiremold 500 and 700 Series raceway connections.

What’s included with the B32? You get the 2-gang outlet box base, matching cover, and mounting screws for the cover. Raceways and electrical devices sold separately.

Will standard devices fit this box? Yes. The B32 accepts standard and commercial-grade 2-gang wiring devices including dimmers, GFCIs, switches, and receptacles.

Why do some users report screw threading issues? The powder coating can partially fill the screw threads. Run a tap through or carefully thread the device screws to clear the coating before final installation.
