Milbank ANSI 61 Gray G90 Galvanized Steel Lay-In Wireway

Milbank ANSI 61 Gray G90 Galvanized Steel Lay-In Wireway

The Milbank ANSI 61 Gray G90 Galvanized Steel Lay-In Wireway is a family of code-ready raceway sections engineered to organize and protect electrical conductors in commercial, industrial, and institutional facilities. This wireway line is available in multiple sizes, ranging from 4-Inch x 4-Inch cross sections in 24-Inch and 60-Inch lengths up to a 6-Inch x 6-Inch x 12-Inch section, with knockouts included on select lengths. Every section is fabricated from G90 galvanized steel and finished in an ANSI 61 gray polyester powder coat — a widely recognized industrial color standard used on switchgear, panelboards, and electrical enclosures. As a lay-in style wireway, the design allows electricians to lay conductors directly into the trough rather than pulling them through a closed conduit run, reducing installation time and simplifying future circuit changes, additions, or maintenance. Whether used as a standalone wiring section or combined with additional wireway lengths and accessories to build out a longer run, this Milbank line delivers the strength and corrosion resistance electrical contractors expect from a steel raceway system.

Key Features

• Available Sizes: select from 4-Inch x 4-Inch x 24-Inch, 4-Inch x 4-Inch x 60-Inch, or 6-Inch x 6-Inch x 12-Inch sections to fit the length and capacity of the run.
• Knockout Options: the 4-Inch x 4-Inch x 24-Inch and 6-Inch x 6-Inch x 12-Inch sections are supplied with knockouts, while the 4-Inch x 4-Inch x 60-Inch section ships with no knockouts for applications requiring a closed enclosure.
• Durable Steel Construction: fabricated from G90 galvanized steel, offering strong corrosion resistance and long service life in demanding commercial and industrial environments.
• ANSI 61 Gray Finish: finished in an ANSI 61 gray polyester powder coat, a standard industrial color that provides a uniform, professional appearance consistent with panelboards and other electrical gear.
• Polyester Powder Coat Protection: the polyester powder coat finish adds an extra layer of protection against scratching, chipping, and environmental wear compared to standard paint finishes.
• Lay-In Trough Design: the lay-in configuration lets conductors be placed into the wireway rather than pulled, reducing labor and easing future wiring modifications or additions.
• G90 Gauge Steel: built to G90 gauge steel specifications for consistent wall thickness and structural integrity across every section in the line.
