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.

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.

Clamp onto metal tubes such as pipe, scaffolding, and railing to hang lighting fixtures, threaded rod, and equipment. Made of aluminum, all of these clamps are lightweight and have good corrosion resistance.

Clamps with a black anodized finish blend into dark backgrounds and are more corrosion resistant than unfinished clamps.

Style A clamps have grooves on the inside to improve grip. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.

Style B clamps have a T-handle for attachment and removal. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.

Style C clamps have wing nuts for making adjustments. Remove the wing nut from the bottom bolt and reattach after mounting equipment.

Style D clamps have a wing nut and a bolt for making adjustments. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.
