Eaton B32A-120SS4 Strut Back-to-Back Welded Channel - Stainless 304, 12 Gauge
Part Number: B32A-120SS4
Quick Summary
Eaton B32A-120SS4 is a back-to-back welded strut channel for heavy electrical and mechanical support. In projects with space constraints or harsh environments, designers often struggle to find durable, install-ready channel solutions. Certifications for this variant are Not Applicable in Eaton’s catalog, so verify CE, SIL, or IP requirements before selection. Its stainless steel 304 finish and 12 gauge body offer corrosion resistance, while standard fittings enable fast, scalable deployment. This combination supports longer service life, reduced maintenance, and predictable installation timelines for industrial facilities, data centers, and manufacturing floors. Secondary keywords such as strut channel, B-Line, and industrial mounting are reinforced by these core features and business benefits.

FAQs
The B32A-120SS4 is designed for heavy electrical and mechanical support in constrained spaces such as data centers, manufacturing floors, and plant rooms. Its back-to-back welded channel enables dual-row mounting, supporting conduits, cable trays, and equipment with strong load capacity. Use it where long-term corrosion resistance and reliable structural integrity are priorities to minimize maintenance downtime and maximize system uptime.
B32A-120SS4 is built to align with standard Eaton Channel and Combinations catalog components, ensuring straightforward procurement and a wide range of compatible fittings. This compatibility reduces fabrication time, simplifies splicing and extensions, and allows faster on-site assembly. For installers, this means fewer surprises during integration and a smoother project timeline.
According to Eaton’s catalog, the B32A-120SS4 lists certifications as Not Applicable for this variant. If your project requires CE, SIL, or IP ratings, verify with your procurement team or select an alternative model that explicitly meets those standards. Always align material selection with your facility’s safety and regulatory requirements to avoid compliance gaps.
Ensure proper alignment of both channel runs to prevent torsional stress in dual-row configurations. Use compatible fittings and hardware rated for 12 gauge steel and stainless finish to maintain corrosion resistance. Pre-assemble sections on the bench when possible, and plan for adequate support intervals to minimize deflection under load, improving long-term stability and reducing maintenance needs.
This model uses steel with a stainless steel type 304 finish and 12 gauge construction. The 304 stainless finish provides excellent corrosion resistance in moderate to harsh environments, including exposure to moisture and some chemical cleaners. The 12 gauge thickness offers robust structural strength, supporting heavy loads and long service life in demanding applications such as process areas and washdown zones.
