GRT NK wiring trough
Standardized dimensions and durable steel construction define the 4496 GRT NK. With 4" height, 4" width, and 96" length, it provides a consistent channel for wiring in control panels, equipment racks, and exterior enclosures. The 16-gauge steel, finished in ANSI 61 gray, offers rugged rigidity and corrosion resistance while maintaining a clean industrial appearance. This combination enables engineers to ship, assemble, and commission panels faster, reducing project lead times and field rework. Mounting efficiency is improved by embossed thru holes and standard mounting patterns. This allows embossed holes to align with common fasteners, eliminating guesswork during installation. Business impact: fewer misdrilled holes, reduced rework, and faster panel assembly translate to lower labor costs and shorter commissioning windows. Application: ideal for high-mix, mid-volume builds where repeatable installation is critical, such as manufacturing lines and process automation cells. No knockouts and secure closure system. The trough uses plated screws and a flange-secured cover, ensuring the lid stays closed in vibration-prone environments and adverse weather. Business impact: reduces ingress risk, supports safe operation, and minimizes maintenance calls. Application: suitable for outdoor and damp locations (NEMA 3R), and for areas with physical impact or frequent door cycling. Certifications and safety compliance. CSA Certified and UL Listed, combined with NEMA 3R enclosure protection, simplify compliance documentation and third-party audits. Business impact: minimizes risk of non-conformance and accelerates project sign-offs. Application: data centers, utilities, and EPC projects where regulatory adherence matters. System compatibility. Designed to integrate with Eaton B-Line series accessories for scalable layouts and consistent cable management across multi-rack installations. Application: retrofit projects and new builds; pairing with embossed thru holes, and covered by ANSI gray finish ensures long-term compatibility and a uniform look.
