GRT NK wiring trough
This trough uses 16 gauge steel with an ANSI 61 gray finish, delivering a robust, corrosion-resistant enclosure channel. The heavy wall thickness minimizes denting from routine maintenance and provides long service life in demanding industrial environments. For electrical and control wiring routed in machine rooms, warehouses, and outdoor areas, the finish supports standardization and compliance without staining or discoloration, improving installer acceptance and asset lifespan. The 6 in by 6 in cross-section and a 96 in length enable consistent footprints across multiple panels. Embossed thru holes for mounting enable quick, repeatable installation along panels and enclosures. The embossed pattern aligns with conventional hardware and preps a consistent mounting grid, shortening assembly time and reducing field rework. In practice, this feature translates to faster panel upgrades and easier reconfiguration as wiring needs evolve. Compatibility with common fasteners simplifies procurement and reduces part variety in a warehouse. No knockouts and a secure cover kept in place by a flange and plated screws simplify cable management and maintain a clean appearance. This design reduces dust ingress and prevents cover loss during maintenance, while allowing service access without disturbing adjacent runs. The screw-on cover supports tool-free inspections and safer cable routing under NEMA 3R conditions. With a 96 inch length, this trough minimizes field joints and supports long, uninterrupted wiring runs between cabinets. The uniform footprint plus 6 inch by 6 inch cross-section creates predictable staging, enabling straightforward inventory planning for controlled environments and faster deployment on site. The combination with embossed thru holes also improves vibration resistance in factory floors. Certified by CSA and UL, and specified for NEMA 3R protection, this trough aligns with regulatory standards and installer expectations. The combination of heavy-gauge steel, secure closure, and durable ANSI 61 gray finish offers a cost-effective, long-term solution for perimeter wiring paths in commercial facilities. Buyers gain predictable maintenance intervals and improved total cost of ownership through standardized Eaton components.

FAQs
The 6696 GRT NK is designed to integrate with Eaton's B-Line wiring trough family, sharing the same footprint and mounting patterns. It uses embossed thru holes for quick, repeatable mounting along 96 in runs and aligns with standard hardware. This compatibility reduces part variety and speeds up panel upgrades. It also supports module-based expansions without rework.
Plan for a two-person lift given its 41.946 lb weight, and use the embossed thru holes to secure the trough with plated screws. No knockouts are provided, so plan wiring routes accordingly. The 6x6 cross-section fits typical panel spacing, and the 96 in length minimizes joints. Prepare anchor hardware in advance and verify clearances to ensure service access remains unobstructed.
Yes. With a NEMA 3R rating and ANSI 61 gray 16-gauge steel, the trough performs well in protected outdoor and washdown environments. Ensure installation follows appropriate enclosure guidelines and keep the cover secured with the flange and screws to maintain weather resistance. Consider operating conditions such as humidity, temperature, and chemical exposure typical to your facility, and ensure that any outdoor run remains protected by enclosure housings and proper mounting hardware.
CSA Certified and UL Listed markings indicate compliance with safety and performance standards, enabling use in regulated facilities. These certifications support risk reduction, easier supplier qualification, and smoother acceptance during facility audits. Additionally, a NEMA 3R rating and ANSI 61 gray finish contribute to reliability in harsh environments and visual compliance with electrical codes.
Standardization across panels, reduced installation time due to embossed thru holes and secure screw covers, and durable 16-gauge steel construction with ANSI 61 gray finish cut maintenance costs and downtime. The long 96 in length minimizes field joints, improving total cost of ownership in growing facilities.
