Wiremold BW3 700 Series 1-Gang Deep Metal Raceway Box

Wiremold BW3 700 Series metal raceway 1-gang deep outlet box provides a durable, paintable on-wall solution for adding or extending power where traditional in-wall wiring isn't practical.

The BW3 700 Series is a heavy-duty metal raceway accessory designed to accept standard or oversized switches, outlets, dimmers and GFCIs while mounting to concrete, brick or other challenging surfaces. Finished in white and 1 3/8" deep, this 1-gang box creates a secure, code-friendly termination point when transitioning between nonmetallic raceway and conduit. It’s made in the USA and engineered for straightforward installation on remodeling, renovation and retrofit projects where surface-mount wiring is preferred.

How does this raceway box help when working on brick or concrete walls?

The BW3 box is built for heavy-duty applications where recessing a junction box isn’t feasible. Its metal construction anchors securely to masonry and supports larger devices without compromising safety or appearance.

• Durable metal housing resists impact and supports frequent use.
• Designed to sit on-wall, avoiding costly wall chases or demolition.
• Compatible with conduit-to-raceway transitions for masonry installations.
• Paintable white finish allows it to blend with surrounding surfaces.

Will this support oversized devices like dimmers or GFCIs?

Yes — the 1 3/8" deep profile accommodates standard and many oversized devices, giving you room for larger switches, dimmers and GFCI outlets without crowding conductors. The extra depth helps maintain proper wire bend radius and simplifies wiring in tight spaces.

• One-gang footprint with deeper interior for bulky devices.
• Accepts common device mounting patterns used in residential and commercial settings.
• Internal space reduces risk of crushed or kinked wires during installation.
• Works with common faceplates and cover styles for a finished look.

How straightforward is installation for a DIY or pro installer?

Wiremold designed the BW3 for straightforward mounting and wiring. It fastens easily to flat surfaces and integrates cleanly with nonmetallic raceway and conduit systems, making it suitable for experienced electricians and competent DIYers tackling surface-mount power runs.

• Sleek profile and preformed mounting points speed alignment and attachment.
• Compatible with Wiremold raceway components to reduce custom fitting.
• Used commonly for smoke detectors, ceiling fans, light fixtures and small power drops.
• Instructions and common practice avoid need for in-wall cutting on many projects.

What are the product quality and finish details?

Manufactured by Wiremold in the USA, the BW3 700 Series emphasizes reliability and component compatibility. The paintable white finish helps the box blend into interiors while the metal construction stands up to tougher jobsite conditions than plastic alternatives.

• Made in USA metal construction for longevity and code compliance.
• Paintable white finish matches décor after painting.
• Designed to interoperate with other Wiremold raceway products for neat installations.
• Ideal for residential, institutional and light commercial spaces.

Who is this for? Installers, remodelers and homeowners who need a reliable surface-mounted electrical termination point on masonry or anywhere in-wall wiring isn’t practical will find the Wiremold BW3 ideal. It’s especially useful when adding or extending power for home offices, rec rooms, garages and retrofit projects where neat cable management, device compatibility and durable construction matter.
