Eaton 3372 G NK wireway - UL Listed & CSA Certified
Part Number: 3372 G NK
Quick Summary
Eaton 3372 G NK wireway provides rugged cable management for industrial enclosures. It is designed to organize and protect conductors over long runs while withstanding harsh factory environments. Many panel builds face challenges from missing knockouts, difficult-to-secure covers, and inconsistent finishing that complicate maintenance. The product carries CSA Certified and UL Listed marks, supporting regulatory compliance, along with a NEMA 1 steel enclosure and ANSI 61 gray finish for durable, code-compliant installations. With through-hole mounting, 16-gauge steel, and a screw-cover design, it offers reliable assembly and long service life. This combination reduces field rework and helps maintain wiring integrity, enabling faster installs and predictable performance in electrical distribution and control panels.

Size and construction matter: The 3372 G NK wireway measures 3 in by 3 in by 72 in and uses 16-gauge steel with ANSI 61 gray finish. This robust build delivers stiffness and resistance to impacts in dense panel assemblies, reducing sag and misalignment. It is ideal for long channel runs in electrical enclosures and retrofit projects, delivering predictable support for wire routing and component mounting. Through-hole mounting provides precise alignment and compatibility with standard mounting patterns, enabling faster, more reliable installations and cleaner cable pathways across equipment racks. The absence of knockouts minimizes field fabrication, reducing labor time and customization costs while maintaining routing integrity. Closure type with plated screws ensures the cover stays secured, limiting dust ingress and preventing components from loosening during vibration, a common concern in industrial settings. Certifications, including CSA Certified and UL Listed, underpin safety and regulatory compliance for regulated industries. Finish and material choice enhance corrosion resistance and overall durability for ongoing maintenance cycles.

FAQs
To install, align the thru holes with pre-existing mounting patterns and secure the wireway with compatible fasteners. The design accommodates long runs and minimizes the need for knockouts, reducing field fabrication steps. Ensure the enclosure is NEMA 1 rated and grounded according to your panel specifications, and verify finish compatibility with the surrounding environment.
Yes. The 3372 G NK is part of Eaton's B-Line wireway family and is designed to integrate with common B-Line components, mounting brackets, and closure systems. This compatibility supports scalable layouts, easier field upgrades, and streamlined cable routing across panel builds.
The wireway is CSA Certified and UL Listed, confirming electrical safety and compliance with recognized standards. These certifications help meet regulatory requirements for many industrial facilities and reduce compliance review time during audits, especially for equipment installed in enclosed indoor environments.
A 16-gauge steel wall provides structural strength to resist flexing and impact in busy panels, while the ANSI 61 gray finish offers corrosion resistance and a consistent, maintenance-friendly appearance. Together they extend service life in demanding manufacturing or processing environments with periodic cleaning and exposure to pollutants.
The combination of thru-hole mounting, no knockouts, and a screw-secured cover speeds installation, reduces field modifications, and lowers labor costs. CSA and UL certifications mitigate risk during inspections, while the durable finish lowers maintenance costs over the product life, delivering faster time-to-operational efficiency and predictable performance.
