Rugged steel construction delivers long-term durability in demanding environments. The 16-gauge steel, 6 in height, 6 in width, and 48 in length provide a robust channel that accommodates substantial cabling while maintaining a compact footprint. This translates to fewer field fabrications and more predictable enclosure layouts, improving overall project timelines. The ANSI 61 gray finish offers corrosion resistance and a consistent aesthetic across installations, helping teams meet facility color and protection guidelines. Embossed thru holes enable quick, drill-free mounting to panels and frames, reducing installation time and potential misalignment. No knockouts in the trough body means you can customize routing without unwanted openings, enhancing cable protection and compliance. The cover is secured by a flange and plated screws, maintaining integrity in vibration-heavy environments and simplifying maintenance. As part of the Eaton B-Line series, it integrates smoothly with other B-Line components, reducing procurement complexity and enabling scalable layouts. Certifications and ratings underpin safety, enabling confident use in diverse applications from data centers to industrial automation rooms. Overall, the GRT NK wiring trough delivers predictable performance, ease of installation, and reduced lifecycle costs for electrical infrastructure projects.
