Eaton 4448 GRT Wiring Trough - CSA UL Listed, 16 ga

Durable steel construction delivers robust mechanical protection and long service life in demanding environments, reducing replacement costs and downtime for critical electrical runs. The 16 gauge thickness paired with ANSI 61 gray finish offers corrosion resistance and a clean, code-compliant appearance, helping you meet maintenance cycles and audit requirements across facilities. With 4 inch height, 4 inch width, and 48 inch length, this GRT wiring trough accommodates substantial cable density while preserving accessible interior spaces for future expansions. Embossed thru holes simplify mounting alignment and secure fasteners, speeding field installation and ensuring repeatable performance on multiple panels. Fifteen bottom knockouts provide flexible entry points for power and data cables, minimizing bending and stress on conductors. A secure screw-covered lid, held by a flange and plated screws, reduces incidental openings and protects contents in dusty or humid environments. Compatibility with Eaton B-Line series components facilitates modular, scalable panel assemblies and reduces inventory variety for contractors. The product’s CSA Certified and UL Listed status streamlines compliance documentation, while NEMA 3R rating confirms suitability for indoor/outdoor installations, improving long-term asset management and repair planning. By choosing this trough, engineers gain predictable installation times, reduced field adjustments, and improved system reliability across automation and electrical infrastructure projects.
