GRT NK wiring trough
The trough uses 16 gauge steel with an ANSI 61 gray finish, delivering rugged durability while maintaining a clean, uniform appearance across facilities. With a 4x4 cross-section and a full 120 inch length, it provides ample routing space for complex cable runs, reducing clutter and improving airflow in electrical rooms. This translates to faster wiring, easier future modifications, and fewer reworks during panel fabrication. CSA Certified and UL Listed ensure compliance with safety standards, while the NEMA 3R rating supports outdoor and damp-location installations, lowering the risk of damage from moisture or weather exposure. Embossed thru holes enable quick, secure mounting with standard fasteners, and the screw cover held by a flange with plated screws keeps wiring tidy and resistant to snagging during service. No knockouts preserve enclosure integrity and protect conductors from incidental damage. The trough is designed for seamless compatibility with Eaton B-Line series accessories, enabling scalable designs that reduce procurement complexity and total cost of ownership. In practice, teams gain reliable, repeatable installations for control panels, machine enclosures, and utility rooms, even as plant layouts evolve.
