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. Zinc-plated steel clamps have good corrosion resistance. 304 stainless steel clamps have excellent corrosion resistance and good chemical resistance. 316 stainless steel clamps have excellent corrosion and chemical resistance.

Beam Clamps for Strut Channel
Support strut channel at a right angle to the beam.
Style B clamps have a plate on the bottom that slides into the strut channel and a locknut to prevent loosening. A threaded hole on the bottom supports threaded rod.
Style C clamps wrap around the strut channel and have a locknut to prevent loosening. It has a threaded hole on the bottom for supporting threaded rod. These clamps should be used in pairs; the capacity listed is for when clamps are used in a pair.
Zinc-plated steel clamps have good 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.

Threaded Rod Mounts
Fasten these brackets to ceilings, walls, beams, and joists to hang threaded rod.
Style A mounts install flush against the ceiling. They are also known as nut plates. To use, screw threaded rod directly into the threaded hole.
Style B mounts have an offset bracket that attaches to the ceiling. To use, screw threaded rod directly into the bracket.
Style C and style D mounts have an offset bracket that attaches to the wall. To use, screw threaded rod directly into the bracket.
Style E and style F mounts install flush against the wall. To use, insert threaded rod into the mounting hole and secure with a nut (not included).
Zinc-plated iron mounts have good corrosion resistance. 304 stainless steel mounts have excellent corrosion resistance.
Note: Capacity is for the mount only. Mounting surface and fastening hardware will affect the ultimate capacity.
