Milbank 4418-GSC1 Wireway Screw Cover NM1

Product Description

The MILBANK 4418-GSC1 is a screw-cover wireway designed for organized routing and protection of electrical conductors in commercial and industrial installations. The screw-on cover provides secure access to the wireway interior for wire pulls, inspections, and service work. This type of wireway is typically installed in switchgear rooms, motor control centers, and panel distribution areas where conductors must be routed in an orderly, code-compliant manner. Licensed electricians and electrical contractors handle installation and termination work on this type of enclosure component.

The 4418-GSC1 screw cover is suited for use with NM1-rated wireway systems in commercial and light industrial environments. It is appropriate for applications requiring a removable, fastened cover that stays securely in place once installed, reducing the risk of accidental opening. This cover is used wherever the corresponding wireway trough is installed along wall runs, above cable trays, or in equipment rooms requiring conductor management infrastructure.

Key Features

• Screw-fastened cover design for secure closure and controlled access
• NM1 wireway rating suitable for commercial and industrial conductor routing
• Provides protection for enclosed conductors against physical damage and contaminants
• Compatible with the corresponding MILBANK wireway trough section

Compatibility

Designed as an OEM-style screw cover replacement for NM1-rated wireway trough systems. Confirm trough model and cover dimensions before ordering to ensure proper fit.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 376 governing metal wireways. De-energize all circuits within the wireway before removing or installing the cover. Secure all screw fasteners evenly to ensure a flush, gap-free fit along the trough. Verify that conductor fill does not exceed the allowable percentage per applicable NEC requirements before closing the cover.
