Milbank G90 Galvanized Steel Lay-In Wireway Gutter

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.
