High load capability meets demanding installations. The 1400 lb load rating delivers margin for lighting fixtures, equipment masts, and conduit runs, reducing the need for alternate supports. In practical terms, this means faster installs and fewer rework calls in commercial and industrial facilities. Precise fastening with 1/2”-13 rod and setscrew ensures reliable engagement. The included setscrew provides positive retention and simplifies torque control, while compatible 1/2”-13 hardware supports quick field assembly on standard strut channels. Beam thickness compatibility at 0.313 in minimizes interference with adjacent components. The clamp design integrates smoothly with Eaton's B-Line system, enabling clean, repeatable installations and easier retrofits. Durable steel construction with a protective finish delivers long service life in demanding environments. The product’s safety factor of 5 reinforces design integrity, helping you meet uptime and regulatory targets. Certification and compatibility packaging: cULus Listed confirms compliance for electrical installations, and compatibility with Eaton's comprehensive B-Line system ensures scalable layouts and future expansion.
