FAQs
For proper installation, confirm the beam width is 0.875 in and the screw size is 1/2-13. Aligning the clamp with the beam flange before tightening ensures a secure grip. Use a compatible driver, finger‑tighten, then snug the setscrew to the manufacturer's torque guidelines, monitoring for any movement under vibration. This approach minimizes repositioning and reduces installation cycle time.
The B309HDG beam clamp provides a 1500 lb load rating and uses a 1/2-13 setscrew. This combination delivers a robust, margin-rich connection suitable for mid to heavy lighting loads and emergency fixtures. Always verify cumulative loads in your installation and distribute weight to avoid exceeded ratings on single clamps.
Yes. The B309HDG is designed for Eaton B-Line strut channels with a 0.875 in beam width. Its 2.5625 in height and 2.5 in length are optimized for secure seating on standard B-Line beams, simplifying procurement and ensuring consistent performance across installations.
The B309HDG is cULus Listed, providing UL safety compliance for electrical installations. This certification supports code adherence and reduces inspection time. Note that data does not indicate CE or IP ratings; plan accordingly if those certifications are required for your project.
Common applications include mounting luminaires, emergency lighting fixtures, and other electrical hardware to B-Line strut systems in commercial and industrial environments. The clamp’s 1500 lb capacity, 0.875 in beam width compatibility, and included setscrew streamline installations in warehouses, manufacturing floors, and retrofit projects, delivering reliable support with minimal rework.
