Seismic Bracing Anchors and Brackets
These OSHPD approved anchors and brackets support threaded-rod-mount hangers during seismic activity. A complete seismic bracing system consists of an upper bracket, a lower bracket, and strut or pipe (sold separately). Brackets work with standard-wall (Schedule 40) pipe sizes 1-2 as well as 1 5/8" wide strut channel. Mount the upper bracket directly to a ceiling or other flat surface, or use an anchor to mount the system to angles, beams, and joists.
Upper brackets connect to the upper end of the strut or pipe. Mount directly into the ceiling, or combine with a beam anchor or angle iron anchor for additional mounting options. Brackets have a hinge that allows the system to sway during seismic activity.
Lower brackets connect threaded rod to the lower end of the strut or pipe. They have a hinge that allows the system to sway during seismic activity.
Angle iron anchors allow you to mount upper brackets to pairs of angles, such as those used in ceiling joists. Their set screws have heads that break off when the screw is tightened to ensure proper installation.

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.
