FAQs
For secure installation, align the clamp with the beam flange and use the 1/2-13 setscrew to achieve a tight grip without over-torquing. Ensure the clamp sits flush to prevent cable or tray interference, and verify load distribution remains within the 1500 lb rating. Use compatible Eaton B-Line components for best fit and ease of maintenance.
The B309ZN beam clamp has a load capacity of 1500 lb and uses a 1/2-13 setscrew. This combination provides strong clamping force while accommodating standard strut and beam assemblies. In practice, verify combined load paths and confirm that the clamp remains within the safety factor requirements for the application.
Yes. The B309ZN is designed as part of the Eaton B-Line series, ensuring compatibility with standard B-Line strut channels, beams, and accessories. This compatibility facilitates modular assemblies, easier future upgrades, and streamlined procurement across projects that already utilize Eaton’s strut system.
The B309ZN carries a cULus Listed certification, confirming compliance with safety standards for electrical installations in North America. This certification helps support regulatory approvals, reduces risk during inspections, and improves customer confidence in performance under typical service conditions alongside the product’s safety factor of 5.
ROI comes from faster installation, reduced rework due to secure grip, and lower maintenance costs from reliable vibration resistance. The clamp’s compatibility with existing B-Line components simplifies replacements, while its robust load rating and safety factor minimize the need for frequent hardware changes in busy electrical rooms and data centers.
