Installation Notes

Installation is typically performed by licensed plumbing or mechanical contractors following IFGC, IPC, or applicable local mechanical codes. Power down or de-energize any nearby electrical components before working in congested ceiling or mechanical room spaces. Ensure the structural member to which the clamp is attached is rated to carry the combined load of the rod, hanger, and supported pipe or equipment. Tighten the locknut securely after positioning the rod to prevent movement under load or vibration.
