Installation Notes

Threaded rod of this type is typically installed by licensed plumbers, electricians, or HVAC mechanics using standard hand and power tools. De-energize all nearby electrical circuits and shut off relevant systems before beginning overhead work. When cutting or shaping the rod on site, dress the cut end to remove burrs before threading on hardware. Follow applicable codes including NEC, IPC, and IFGC for proper hanger spacing and support requirements in your jurisdiction.
