Milbank Lay-In Wireway Section, Sectional Steel Enclosure

Milbank Lay-In Wireway Section, Sectional Steel Enclosure

The Milbank Lay-In Wireway Section is a sectional steel enclosure family used to organize, route, and protect power and control conductors in commercial and industrial electrical systems. This wireway line is available across a wide range of configurations, spanning cross-sections from 4-Inch x 4-Inch up to 12-Inch x 12-Inch and lengths from 12-Inch through 72-Inch, so contractors and engineers can select the exact section size needed for a given run. Sections are offered in both Gray and Unpainted finishes, and in With Knockouts or No Knockouts (NK) configurations, giving installers the flexibility to choose a pre-punched section for standard routing or a no-knockout section when conductor entry and exit points need to be field-located to match a custom installation. Every option in this family shares the same lay-in trough design, allowing conductors to be laid into the wireway rather than pulled through conduit, which simplifies both initial installation and future access for maintenance or circuit changes.

Key Features

• Trade Size Range: Cross-sections from 4-Inch x 4-Inch through 12-Inch x 12-Inch and lengths from 12-Inch through 72-Inch, selectable to match the specific run.
• Lay-In Design: Conductors can be laid into the wireway trough for organized routing and easier future access compared to pulling wire through conduit.
• Knockout Configuration Options: Available With Knockouts for standard conductor entry points, or No Knockouts (NK) for installations where entry and exit points must be field-located.
• Finish Options: Offered in Gray or Unpainted finish depending on the selected configuration.
• Sectional Design: Functions as a building-block section within a larger Milbank wireway run, panelboard, or distribution system, allowing runs to be extended as needed.
• Model Family Designation: Sections in this family follow the GSC1 designation pattern for accurate specification, ordering, and matching to compatible Milbank wireway components.

Technical Specifications

• Enclosure Size / Knockout & Finish: 14 selectable options spanning 12-Inch x 12-Inch x 12-Inch through 72-Inch x 4-Inch x 4-Inch, in Gray or Unpainted finish, With Knockouts or No Knockouts.
• Refer to manufacturer documentation for complete technical specifications on the selected configuration.

Typical Applications

• Commercial and Industrial Electrical Installations
• Conductor and Cable Routing Between Enclosures
• Panelboard and Switchgear Interconnections
• Custom Field-Drilled Wireway Runs (No Knockout Configurations)
• New Construction and Retrofit Wiring Projects

Why Milbank?

Milbank wireway sections are built to serve as dependable, interchangeable components within larger electrical distribution and wire management systems. Offering this section across multiple cross-sections, lengths, finishes, and knockout configurations gives contractors and engineers the flexibility to specify exactly what a given run requires, whether that means a pre-punched section for standard routing or a no-knockout section for custom field-located conductor entries. For engineers and contractors specifying wireway systems, having a clear range of sizes and configurations under one family designation simplifies bill-of-materials planning and coordination with other enclosure components. Choosing Milbank for wireway sections helps ensure a consistent fit and finish across a commercial or industrial wire management system.
