FAQs
To install, position the clamp around the steel beam and align with the B-Line strut channel. Thread a 7/8"-9 rod into the clamp, then tighten to achieve vertical adjustment and secure the assembly. Confirm that the clamp remains aligned after initial load application and re-tighten as needed. This approach minimizes drift during commissioning.
The 7/8"-9 thread size is designed to mate with standard threaded rods used in overhead supports. Ensure the rod is clean and free of debris before insert and tighten to the recommended torque. The vertical adjustment capability helps compensate for misalignments, improving installation accuracy and reducing rework after initial load testing.
Yes. The clamp is designed for B-Line strut systems used in electrical and lighting applications, including data centers. Its steel construction and vertical adjustment provide secure mounting for conduits and fixtures, while the 5x8x8 in footprint helps maintain consistent spacing. Verify compatibility with your specific channel size and rod length prior to installation.
The B3055-7/8X8PLN is cULus Listed, signaling compliance with US and Canadian electrical safety standards. This certification supports code compliance during audits and reduces the risk of non-conformance in regulated facilities. Users should still follow project-specific requirements and local codes for overall system certification.
The clamp’s durable steel construction and integrated vertical adjustment reduce rebedding and readjustment time during retrofit projects. Its compatibility with existing B-Line systems minimizes accessory purchases, lowering total installed cost. Over the life of the installation, fewer loosening incidents mean improved uptime and reduced maintenance visits.
