Eaton Specification Sheet - B22A-120HDG
Dura-Green finish overview
The Eaton B22A-120HDG Strut Channel is built from hot-dipped galvanized steel in 12 gauge, delivering strong, durable support for critical infrastructure. This translates to improved load handling and corrosion resistance in harsh environments, allowing more reliable cable management and equipment mounting in manufacturing floors and data centers. The back-to-back welded channel design enables dual-rail configurations, reducing the need for extra bracing and enabling faster system integration with existing B-Line components. Because the channel is part of the B-Line ecosystem, installers benefit from standardized fittings, nuts, bolts, and brackets that fit precisely, minimizing field adjustments and wasted downtime. The 12 in length per segment is ideal for modular, scalable framing, while real-world handling remains manageable with a weight of 3.584 lb per piece. The hot-dip galvanization ensures long-term durability in damp or corrosive environments, lowering maintenance cycles and overall lifecycle costs. Complementary accessories and compatible supports further streamline installation, allowing engineers to design safer, code-compliant frames with predictable performance.
