Milbank G90 Galvanized Steel Lay-In Wireway Gutter

The Milbank Lay-In Wireway Gutter is an enclosed steel raceway built to organize, route, and protect branch-circuit conductors between panelboards, switchgear, and other electrical equipment. This wireway family is available in sizes ranging from 12" x 4" x 4" up to 48" x 10" x 10", with housing finish options including ANSI 61 Gray and Unpainted Galvanized, so contractors can match a wire management run to the panel lineup or switchgear layout on hand. The lay-in design lets installers set conductors directly into the wireway channel instead of fishing or pulling them through a closed conduit run, which can meaningfully reduce labor time on panel lineups, switchgear rooms, and industrial control layouts. Every size and finish in this family is fabricated from G90 galvanized steel for long-term corrosion resistance, and the unpainted variants ship ready for immediate installation or for field painting to match surrounding equipment.

Key Features

  • Size Range: Available from 12" x 4" x 4" through 48" x 10" x 10", providing an enclosed channel for wire and cable routing between electrical equipment.
  • Durable Construction: Fabricated from G90 galvanized steel across the size range for long-term corrosion resistance in electrical rooms, industrial plants, and other demanding environments.
  • Lay-In Design: Conductors can be laid into the wireway channel rather than pulled through, reducing installation time and labor on the job site.
  • Finish Options: Offered in ANSI 61 Gray or Unpainted Galvanized steel, letting installers use the wireway as-is or field paint unpainted sections to match adjacent equipment.
  • Gutter Wireway Configuration: Designed to connect with compatible Milbank gutter and wireway sections, supporting extended conductor runs between panels and switchgear.
  • Enclosed Steel Housing: The steel gutter body helps protect conductors from physical damage and contamination while keeping wiring organized and accessible.

Technical Specifications

  • Sizes: 12" x 4" x 4" (ANSI 61 Gray), 24" x 6" x 6" (Unpainted Galvanized), 48" x 10" x 10" (Unpainted Galvanized).
  • Material: G90 Galvanized Steel.

Typical Applications

  • Wire and Cable Management in Electrical and Switchgear Rooms
  • Panelboard and Panel Lineup Wiring Gutters
  • Commercial and Industrial Electrical Installations
  • Junction and Distribution Point Wire Routing
  • New Construction and Electrical System Expansions
  • Connecting Runs Between Panelboards and Switchgear

Why Milbank?

Milbank builds this gutter lay-in wireway family from G90 galvanized steel to deliver dependable corrosion resistance across every size, from compact 12" x 4" x 4" sections up to larger 48" x 10" x 10" runs. The lay-in configuration reflects a practical, installer-friendly design that helps reduce labor on panel and switchgear wiring projects. With both ANSI 61 Gray and Unpainted Galvanized finish options, Milbank gives contractors the flexibility to install the wireway as-is or finish-paint it to match surrounding equipment, supporting a consistent, code-compliant approach to conductor management across commercial and industrial facilities.

Milbank 4412-GSC1 – Frequently Asked Questions

1) What sizes does the Milbank lay-in wireway come in?
Four sections are offered: 12 x 4 x 4 inch in ANSI 61 Gray, 24 x 6 x 6 inch unpainted galvanized, 48 x 10 x 10 inch unpainted galvanized, and 72 x 10 x 10 inch unpainted galvanized. The small 4 x 4 cross section suits short jumps between adjacent panels; the 10 x 10 cross section in 48 and 72 inch lengths is what you want for a switchgear or panel lineup run carrying a large conductor bundle.
2) Can I get the Milbank wireway in gray, or only unpainted galvanized?
Gray is tied to one size. The 12 x 4 x 4 inch section (part 4412-GSC1) is the ANSI 61 Gray one; the 6 x 6 and 10 x 10 sections ship unpainted G90 galvanized. If you need gray on a larger run, the unpainted steel is made to be field painted to match the adjacent gear.
3) Can I join several Milbank wireway sections into one long run?
Yes. The sections are built to connect with compatible Milbank gutter and wireway sections, so you can chain 48 and 72 inch 10 x 10 lengths end to end for a run along a panel lineup. Keep the cross section consistent across the run, since a 4 x 4 and a 10 x 10 are not the same opening.
4) What is the difference between the Milbank lay-in wireway and the Square D Square-Duct with hinged cover?
Cover style is the main difference. The Square D Square-Duct LDB is a NEMA 1 wireway with a hinged cover, so the cover swings open and stays attached to the body. The Milbank gutter is a lay-in design in which conductors are laid into the channel rather than pulled through, and it is fabricated from G90 galvanized steel in sizes from 12 inches x 4 inches x 4 inches up to 72 inches x 10 inches x 10 inches, in ANSI 61 Gray or unpainted galvanized. Both approaches give open access to the channel during the pull; the choice usually comes down to how the cover is handled on the job and whether you want a galvanized or painted body.
5) I'm standardizing wire gutters across a facility. Can I mix Milbank finishes on the same job?
Yes, and many facilities do. The unpainted G90 galvanized sections can be installed bare in back-of-house electrical rooms and field painted where they run through finished or public-facing spaces, which lets one material spec cover the whole building. The 12 x 4 x 4 inch section comes already in ANSI 61 Gray if you want a factory match to gray gear without painting.
