These OSHPD preapproved 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.

Beam anchors allow you to mount upper brackets to beams, C-channel, ceiling joists, and other flat surfaces. Their set screws have heads that break off when the screw is tightened to ensure proper installation.

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.
