Feature → Business Impact → Application: The 16 gauge steel construction provides robust mechanical strength, delivering long-term durability in harsh environments and reducing the risk of damage from incidental impact in crowded control rooms or manufacturing floors. This translates to lower replacement costs and less downtime during maintenance or upgrades in automotive, food & beverage, or process industries. Feature → Business Impact → Application: ANSI 61 gray finish offers a corrosion-resistant, low-reflectivity surface that minimizes heat buildup and fade over time, supporting compliance with appearance and durability standards in heavy-industrial settings. This is particularly valuable for panel interiors and outdoor installations where exposure to humidity and contaminants is common. Feature → Business Impact → Application: Embossed thru holes and no knockouts enable rapid, repeatable mounting while preserving enclosure integrity, reducing field modification time and potential ingress paths in data centers and machine rooms. Feature → Business Impact → Application: Cover is held secure by a flange and plated screws, ensuring reliable closure even in vibration-prone environments, which lowers rework and improves panel air sealing in packaging and material-handling facilities. Feature → Business Impact → Application: NEMA 3R rating and CSA UL certification provide regulatory assurance for indoor/outdoor installations, helping procurement justify compliance costs and risk management in critical infrastructure projects. Feature → Business Impact → Application: 8 in height, 8 in width, and 18 in length sized for compact installations while maintaining ample internal capacity for wiring bundles, simplifying retrofits and new builds in controls cabinets and electrical rooms. Feature → Business Impact → Application: Mounting method with embossed holes supports quick alignment with existing mounting patterns, compatible with Eaton B-Line accessories and standard enclosure builds, reducing engineering time for panel designers in industrial automation environments. Feature → Business Impact → Application: Plated screws and a secure closure system minimize maintenance calls and vibration-induced loosening, delivering stable cable routing in CNC facilities or material handling plants. Feature → Business Impact → Application: No knockouts maintain enclosure cleanliness and electrical integrity, reducing dust ingress and moisture pathways in aggressive environments like manufacturing floors and washdown zones.

FAQs

The trough uses embossed thru holes for mounting, allowing quick alignment with existing mounting patterns. It features a flange-secured cover with plated screws to seal the channel, and no knockouts to reduce debris ingress. For best results, align with compatible B-Line accessories and follow standard enclosure mounting practices to ensure a tight, vibration-resistant fit.
With 16 gauge steel, ANSI 61 gray finish, and a NEMA 3R rating, the trough is designed for robust indoor and outdoor use. The 8x8x18 dimensions provide ample routing space, while embossed mounting holes facilitate precise installation. CSA Certified and UL Listed certifications confirm compliance with common industrial electrical standards.
Yes. The NEMA 3R rating indicates suitability for outdoor and protected indoor environments, while the ANSI 61 gray finish adds corrosion resistance. For washdown areas, ensure additional protection as needed, but the trough’s gasketless, no-knockout design helps minimize ingress points when used with proper sealing practices.
This trough is CSA Certified and UL Listed, providing third-party verification of electrical and material safety. These certifications support regulatory compliance for industrial facilities, reduce risk in audits, and streamline procurement by meeting common safety and performance standards.
ROI improves through faster builds due to embossed thru holes, simplified mounting, and secure cover assembly with plated screws. The no knockouts feature reduces modification time and potential ingress points, lowering maintenance costs over the product life cycle in automation and processing environments.
