Eaton B305HDG Beam Clamp - cULus Listed
Part Number: B305HDG
Quick Summary
Eaton B305HDG beam clamp secures rods to beam flanges in electrical strut systems. Installers often grapple with set screws that loosen under vibration or load, causing rerouting and downtime. This clamp carries a cULus Listed certification, supports a 600 lb load, and uses a 3/8-16 threaded rod with a 0.875 in beam width, with a safety factor of 5 for added reliability. As part of Eaton's B-Line family, it integrates with standard strut channels, delivering fast, dependable installation for electrical, mechanical, and data-center applications. Engineers benefit from predictable performance, easy field maintenance, and scalable compatibility across projects. Its compact footprint and precise clamp geometry reduce misalignment during mounting.

600 lb load capacity and a safety factor of 5 provide predictable, resilient support for suspended runs in demanding environments. This performance translates to fewer field retightenings, reduced downtime during commissioning, and improved worker safety on crowded install sites. By ensuring a secure hold even when rails vibrate or shift under temperature cycling, the B305HDG minimizes maintenance cycles and supports longer service life for critical electrical and mechanical infrastructure. The 3/8-16 thread, compatible with common strut hardware, and the included set screw simplify installation and precise tensioning. This design reduces the need for specialized tools and minimizes rework caused by loose connections. In retrofit projects or new builds, technicians appreciate the fast, repeatable mounting process that keeps project schedules on track while preserving joint integrity over many years of operation. Compact dimensions—2.3125 in high, 2.5 in long, and 1.125 in wide—enable mounting in tight spaces without sacrificing grip strength. The slim profile complements standard B-Line strut channels and allows clean routing of cables, conduits, and pipes in crowded electrical rooms. When paired with a 0.875 in beam width, the clamp aligns precisely with other components in a modular support system. Durable steel construction with a robust finish resists impact and wear in challenging environments. The B305HDG’s all-metal geometry maintains clamping force over time, reducing the risk of loosened connections after installation and during service life in industrial facilities. cULus Listed certification demonstrates compliance with UL safety standards for electrical equipment, helping you meet regulatory requirements across facilities. This certification, combined with the clamp’s documented load rating and safety margins, supports audits and reduces project risk during procurement and installation. Set screw included and beam/clamp compatibility across Eaton’s B-Line family simplify procurement and inventory management, ensuring you can source matching hardware from a single supplier and speed up maintenance or upgrades.

FAQs
To install, align the clamp with the beam flange and thread the 3/8-16 rod into the corresponding hole. Insert the set screw and tighten to specification to secure the rod without over-torquing. Verify the 0.875 in beam width is compatible with the channel and check that the clamp remains firmly seated under simulated load conditions.
Key specs include a 600 lb load capacity, 3/8-16 rod size, 3/8 inch set screw, 0.875 in beam width, 2.3125 in height, 2.5 in length, 1.125 in width, weight of 0.72 lb, steel construction, and cULus Listed certification. Compatibility with B-Line strut systems is provided by standard beaming dimensions.
Yes. The B305HDG is specifically designed for 3/8-16 threaded rods and 0.875 in beam widths, with exact dimensions of 2.3125 in height, 2.5 in length, and 1.125 in width to ensure a precise fit and reliable performance in standard B-Line strut configurations.
The B305HDG carries a cULus Listed certification, indicating compliance with UL safety standards for electrical equipment. This certification supports regulatory approvals and helps reduce compliance risk in industrial and commercial installations.
The ROI stems from reduced maintenance, fewer retightenings, and faster installation due to the included set screw and straightforward 3/8-16 threading. In high-availability facilities, these gains translate into shorter outage windows, improved worker safety, and lower total project costs over the clamp’s service life.
