Eaton 8872 GRT Wiring Trough - UL Listed, CSA Certified
Part Number: 8872 GRT
Quick Summary
Eaton B-Line series wiring trough securely channels electrical cables in industrial enclosures for clean, organized installations. A common challenge is field wear, misaligned knockouts, and unsecured covers that slow projects and raise safety risks. This model is CSA Certified and UL Listed, with NEMA 3R protection for indoor and outdoor/damp environments. Constructed from 16-gauge steel and finished in ANSI 61 gray, it features embossed thru holes for quick mounting and a cover held secure by flange and plated screws. The 8 in high, 8 in wide, and 72 in long footprint supports substantial cable loads while compatible with standard mounting patterns. This translates to reduced rework, faster commissioning, and easier maintenance for facilities teams.

Generous dimensions and 16 gauge steel construction support high cable density while delivering predictable routing across long runs. With an 8 in height, 8 in width, and 72 in length, the trough accommodates substantial cable bundles and simplifies panel layouts, reducing rework and commissioning time. A durable ANSI 61 gray finish and NEMA 3R rating provide resilience in varied plant environments, improving long-term reliability. Embossed thru holes offer precise mounting alignment and fast installation, minimizing the need for field drilling or custom hardware. This improves consistency across multiple panels and reduces labor costs while enabling clean cable separation and easier future upgrades. The screw cover is secured by a flange and plated screws, delivering a secure, vibration-resistant enclosure. This design reduces accidental cover loosening in heavy equipment settings and enables straightforward removal for maintenance tasks. The ANSI 61 gray finish paired with 16 gauge steel delivers corrosion resistance, consistent color coding, and long service life in harsh environments, supporting code compliance and minimizing repainting or replacement during plant uptime. Certified by CSA and UL and designed for B-Line systems, this trough integrates with standard mounting hardware and accessories, enabling scalable, compliant cabling strategies across facilities.
