Its 1 in height, 1.62 in width, and 120 in length support long spans with back-to-back welded construction. Pair with compatible clips, brackets, and couplers to create rigid back-to-back configurations, reducing misalignment and simplifying sequencing during assembly.
Key specs include 12 gauge stainless steel (type 304) and a weight of 27.2 lb per channel, which influence bending resistance and rigidity. The exact load ratings aren’t listed in the data, so engineers should request Eaton’s engineering guidance for your specific span, attachment points, and accessory load distribution to ensure compliance with your design intent.
Yes. The channel is finished in stainless steel type 304, which offers enhanced corrosion resistance suitable for many industrial environments. It is well-suited for regions with humidity, condensation, or exposure to mild chemicals. For highly aggressive environments, review site-specific corrosion requirements and consider alternate finishes or alloys as needed.
Certifications are listed as Not Applicable for this model. While formal SIL, CE, or IP ratings aren’t indicated, the product aligns with Eaton’s B-Line strut system standards and general industrial mounting practices. Always confirm with your project requirements and any local electrical or mechanical standards before deployment.
The stainless 304 construction and 12 gauge wall deliver durability and resistance to corrosion, reducing replacement and maintenance costs over time. Its compatibility with a full range of Eaton accessories simplifies future upgrades and maintenance, lowering downtime and enabling faster site commissioning for ongoing ROI.
