For All Things Beam Clamps

What Are They?

These clamps are designed to hang threaded rod and other threaded devices from structural members. They are often tapped on the underside and the back to accommodate a variety of threaded rod widths diameters, either vertically or horizontally.

Threaded rod hung from these clamps can accommodate the suspension of low-voltage data communications electrical, HVAC and plumbing and many more types of services, where embedding a rod into a ceiling is not possible, such as on the steel roofs of warehouses.

Beam clamps require no drilling and their adjustability makes it easy to attach them to a variety of beam thicknesses. They are available in a variety of load ratings, materials and finishes. And these clamps are made for different purposes – for attaching to metal or wood structures (with the wood ones requiring a pre-drilled hole in the wood).
