Feature: 16 gauge galvanized steel with a gray finish delivers robust corrosion resistance, outstanding load-bearing strength, and predictable performance in demanding environments. Business impact: This reduces maintenance, extends service life, and lowers total cost of ownership in harsh environments for long-term reliability and fewer field service calls. Application: Ideal for long runs in plant floors or outdoor installations where dependable cable containment is critical. Feature: 4 in height by 4 in width with a 120 in length channel provides substantial cable capacity and a modular routing path that supports multiple circuits. Business impact: This simplifies design, minimizes splices, and reduces field labor during installs, accelerating project timelines and improving first-pass quality. Application: Suitable for runs along equipment rows and control panels where space is constrained and installation speed matters. Feature: Embossed thru holes with no knockouts enable consistent mounting patterns and faster alignment, while offering versatile screw placement. Business impact: Reduces field guesswork, minimizes rework, and accelerates enclosure integration across starter-to-full-scale builds, cutting commissioning risk. Application: Ideal for retrofit projects and new constructions needing clean, repeatable fastening in tight consolidation zones. Feature: Screw cover and flange-secured closure using plated screws keep the cover firmly in place even under vibration. Business impact: Improves vibration resistance and reduces risk of wiring exposure or damage in dynamic environments, lowering warranty costs. Application: Well suited to machinery rooms, transfer lines, and outdoor enclosures where movement occurs and reliability is critical. Feature: NEMA 3R rating and CSA C22.2 UL Listed certifications validate weather resistance, user safety, and long-term durability. Business impact: Compliance streamlines procurement, reduces project risk, and supports regulatory audits with documented performance and traceability. Application: Essential in outdoor installations and damp environments across industrial facilities, including manufacturing floors and data centers. Feature: Part of the Eaton B-Line series with embossed holes and standard galvanized steel construction, designed for consistent installation across jobs. Business impact: Streamlines procurement and long-term maintenance planning by using a common, compatible wiring trough across sites and projects. Application: An ideal choice for electricians, OEMs, and integrators seeking reliable, scalable cable management that supports future expansions.

FAQs

The 44120 GRTGV NK is designed for compatibility with Eaton's B-Line series enclosures, using standard embossed thru holes and a screw-cover closure. It aligns with common mounting patterns and uses plated screws, enabling quick integration with minimal modification. This reduces field adaptation time and ensures a secure, repeatable installation across multiple sites.
The trough is 16-gauge galvanized steel with a gray finish, offering excellent corrosion resistance. It carries a NEMA 3R rating and CSA C22.2 UL Listed certifications, validating suitability for indoor and outdoor use, resistance to dust, moisture, and moderate weather exposure, and compliance with relevant safety standards.
Yes. With a NEMA 3R rating and galvanized steel construction, the 44120 GRTGV NK is designed for outdoor and damp environments. The UL Listed certification further confirms safety and suitability, making it appropriate for exterior panels, enclosures adjacent to equipment, and other environments where moisture and corrosion are concerns.
The 4 in by 4 in cross-section and 120 in length provide substantial cable capacity while maintaining a manageable footprint. This reduces the number of conduits or splices, speeds up layout planning, and shortens installation time. The embossed thru holes enable quick mounting, while the screw-cover closure minimizes rework and ensures a clean, accessible route for maintenance.
Long-term durability from 16 gauge galvanized steel reduces repainting and replacement needs, lowering lifecycle costs. The secure cover and corrosion resistance minimize maintenance interventions, while standardization within the Eaton B-Line family simplifies spare-part availability and procurement, delivering predictable maintenance planning and a higher return on investment.
