GRTGV NK wiring trough
The trough uses 16 gauge galvanized steel for rugged durability and weather resistance. This material choice lowers long-term maintenance costs by resisting corrosion in damp environments. It suits outdoor enclosures, equipment rooms, and process areas where reliability is essential. Embossed thru holes provide precise mounting with standard hardware, reducing alignment errors and installation time. The design supports vibration resistance and faster field assembly, making it ideal for bolting to fixed supports in electrical rooms and equipment racks. No knockouts minimize debris entry and accidental openings during field routing, improving safety and protecting conductors in dusty or outdoor settings. The screw cover is secured by a flange and plated screws, keeping the lid in place against vibration and tampering, which reduces service calls due to loose covers and enhances enclosure integrity. The precise 4"x4"x48" footprint with 16 gauge steel offers predictable fit and straightforward inventory planning, reducing rework and simplifying panel layouts in electrical rooms and equipment bays. Certifications and weather-ready construction ensure compliance and reliable performance in harsh environments, supporting long-term maintenance planning and operational continuity.

FAQs
Embossed thru holes provide precise mounting alignment with standard fasteners, and the trough is designed with embossed mounting points that simplify bolt-in installation. This reduces field errors and aligns with other components in Eaton's B-Line series. For practical use, you can attach to panels, cabinets, or structural supports without special tools.
16 gauge galvanized steel provides rugged durability and corrosion resistance, especially in outdoor or damp locations. This baseline capability reduces maintenance cycles and replacement costs over the product life. The finish protects against rust while providing a uniform gray appearance that helps with visibility and compliance in industrial environments.
Yes. The wiring trough carries CSA C22.2 UL Listed certifications and a NEMA 3R rating, indicating suitability for outdoor and damp indoor environments. The galvanized steel construction augments weather resistance, while the gray finish helps with UV resilience and paint compatibility in facility upgrades.
The trough design minimizes field modifications by providing embossed thru holes for quick mounting and by avoiding knockouts that can invite dust and moisture. The screw-on lid, held by a flange and plated screws, reduces lid detachment during vibration and maintenance access. Together, these features streamline commissioning in busy electrical rooms.
Choosing this trough yields lower lifecycle cost through longer service life, fewer corrosion-related replacements, and faster installation in projects that require CSA/UL compliance. The durable galvanized steel construction and secure cover reduce downtime and maintenance calls, while its standardized 4x4x48 footprint minimizes surprises during panel layout and field modifications.
