OBO Bettermann Vertical Girder Clamp 5-11mm M6 Electrogalvanized Steel 328 1 (1408011)

Unlike generic beam clamps that rely on spring tension or plastic bodies, this OBO Bettermann 328 series clamp grips steel girders with a solid screw-fastened steel jaw, rated for flange thicknesses from 5 to 11 mm. The vertical mounting orientation and integrated M6 internal thread make it a dependable anchor point for threaded rod, cable trays, or conduit supports in dry indoor installations.

Highlights

• Vertical girder clamp for steel profiles, beams, and I/T sections
• Flange thickness range: 5–11 mm, with M6 internal thread
• Electrogalvanized steel body for standard indoor corrosion protection
• Static load capacity up to 100 N (approx. 10 kg)
• Simple screw-on installation with a standard wrench

In daily use

Mounting is straightforward: position the clamp over the girder flange, align the threaded bore, and tighten the screw until the clamp grips securely. The vertical orientation keeps the load path in line with the girder web, reducing bending moments on the flange. The M6 thread accepts common metric threaded rod or bolts, making it easy to integrate into existing support structures. The silver electrogalvanized finish blends with most steelwork and provides adequate protection in dry, non-corrosive environments.
