FAQs
Installers should start with mounting the trough on prepared surfaces using embossed thru holes and plated screws to ensure a secure, vibration-resistant attachment. Avoid forcing through holes on misaligned panels, and use the flange-secured cover system to maintain enclosure integrity. The 36 inch length fits standard B-Line accessories for scalable configurations, and the 6x6 footprint supports multi-cable routing without crowding.
Yes. The trough is designed for compatibility with Eaton B-Line series components. Embossed thru holes and the secure flange-and-screws cover system simplify integration with shelves, brackets, and accessory channels, enabling modular assemblies that can expand with project scope without rework or custom fabrication.
Key specs include: 16 gauge galvanized steel construction, gray finish, 6 inch height, 6 inch width, 36 inch length, NEMA 3R rating, no knockouts, embossed thru holes, and plated screws for the cover. It weighs about 16.357 lb and is UL Listed along with CSA C22.2 certification, making it suitable for protected indoor and semi-exposed environments.
The trough is UL Listed and CSA C22.2 certified, indicating compliance with safety and performance standards for electrical components. The NEMA 3R rating provides protection against rain and corrosion in guarded outdoor or semi-exposed spaces. These certifications help ensure reliability, regulatory compliance, and smoother procurement for regulated industries.
The combination of 16 gauge galvanized steel, durable gray finish, and secure cover design reduces corrosion-related maintenance and rework. Quick installation with embossed holes and plated screws shortens commissioning time, while compatibility with B-Line accessories supports scalable project growth, lowering total cost of ownership across multiple panel builds.
