On busy construction sites and in industrial plants, electricians and fitters need a fast, reliable way to secure threaded rods, pipes, and cable trays to steel girders without drilling or welding. The OBO Bettermann Girder Clamp 328 2 answers that call: it simply snaps onto the flange, grips tight, and provides a solid M8 connection point for your mounting hardware.
