FAQs
The B321-2SS6 supports 1/2"-13 thread/rod size and fits beams with a 0.313 in thickness. It includes a setscrew for secure tightening, and its compact 3.25 in length helps install in tight spaces typical of electrical rooms and strut systems.
This clamp provides a 1400 lb load rating with a safety factor of 5. That means the actual working load is comfortably below the rated capacity, improving reliability for dynamic installations such as lighting fixtures and mechanical supports in industrial environments.
Best suited for lighting and electrical distribution systems that use strut channels, the B321-2SS6 can securely attach fixtures and equipment to beams while maintaining alignment and ease of inspection in facilities like warehouses, manufacturing plants, and data centers.
The clamp is cULus Listed, ensuring compliance with UL safety standards for electrical installations. This certification supports code-compliant installations and reduces procurement risk for regulated facilities.
With an included setscrew, common thread size, and robust load rating, installation is faster and requires fewer spare parts. The result is lower field labor costs, reduced rework, and improved uptimeādriving better ROI for ongoing maintenance and facility upgrades.
