Feature is 350 lb load capacity paired with malleable iron construction, delivering a strong, durable hold that reduces sagging and movement in critical electrical runs. Business impact translates to improved system integrity and fewer field adjustments, especially in high-vibration environments, with applications spanning lighting fixtures, sensors, and electrical distribution along strut systems. The 3/8-16 thread size and compatibility with setscrew and locknut mechanisms enable quick, secure fastening, cutting installation time and minimizing downtime on busy construction sites. Finish is electro-plated zinc, offering corrosion resistance in exposed installations, which lowers maintenance frequency and replacement costs. The clamp’s dimensions—3 in length, 1.875 in height and width—ensure a compact footprint that fits standard B-Line strut channels, maximizing space and simplifying inventory planning. As a compatible option within Eaton’s Strut Systems catalog, it supports modular, scalable layouts for growing facilities. A safety factor of 5 provides an additional margin against unexpected loading, supporting compliance and long-term performance. In practice, installers benefit from predictable torque behavior and reliable performance with standard tools, reducing callbacks and rework while supporting consistent quality across multiple builds.

FAQs
The B444-3/8YZN is designed for Eaton B-Line strut systems and uses a 3/8-16 threaded rod. It integrates with setscrews and locknuts for secure, vibration-resistant connections. Its electro-plated zinc finish offers corrosion resistance ideal for exposed installations, and its 350 lb rated capacity supports a range of lighting and equipment suspensions without sacrificing ease of installation.
Begin by aligning the clamp with the rod and strut channel, insert the 3/8-16 threaded rod, then tighten the setscrew against the rod using the appropriate tool. Follow with the locknut to lock the position and verify the load path. Check the electro-plated finish for integrity and confirm the assembly remains within the 350 lb rating and Safety factor 5.
The B444-3/8YZN is cULus Listed, indicating compliance with recognized safety standards for electrical components used in North American installations. This certification supports regulatory compliance in commercial and industrial facilities, streamlines acceptance with electrical inspectors, and helps reduce project risk when wiring through strut systems and lighting runs.
The clamp is made from malleable iron and finished with an electro-plated zinc coating. This combination provides robust mechanical strength and enhanced corrosion resistance, extending service life in damp or outdoor environments. The durable finish also simplifies maintenance by resisting wear from frequent adjustments and handling during installations and reconfigurations.
Using the B444-3/8YZN reduces installation time due to straightforward mounting with standard tools and a reliable setscrew/locknut mechanism, which lowers labor costs. The 350 lb rating and 5x safety factor provide a generous design margin, reducing maintenance calls and preventing early replacements. The cULus listing further minimizes regulatory risk, supporting long-term reliability and predictable budgeting.
