Beam Clamps for Threaded Rod
Attach these clamps to the flange of a beam, then hang a threaded rod from the threaded hole.
Styles A-C, F-G, and J-L have a locknut to prevent loosening.
Styles D, E, and H have a threaded hole on the back for supporting a hanger or routing ring.
Zinc-plated iron clamps have mild corrosion resistance.

Angle Iron Clamps for Threaded Rod
A secure way to hang threaded rod from a pair of angles, such as those used in ceiling joists, without the need to drill or weld. These clamps are commonly used to suspend HVAC, conveyor, and other overhead systems. They may also be used to connect two pairs of angles at 90°. Clamps are zinc-plated steel for good corrosion resistance. Each clamp includes a bracket and square washer. Secure with a hex nut (sold separately).
Capacity is the maximum load for two clamps holding a pair of angles across parallel joists. The values listed are for the maximum distance between joists, which is 6 ft. For shorter distances, capacities are higher.
