Thomas & Betts H125GR-TB Grounding Conduit Hub

The Thomas & Betts H125GR-TB Grounding Conduit Hub provides a watertight, electrically bonded connection between 1-1/4-inch threaded rigid metal conduit (RMC) or intermediate metal conduit (IMC) and threadless openings in electrical enclosures, delivering a reliable grounding path for control panels, switchboards, motor control centers, outdoor enclosures, and hazardous-location electrical systems. Designed for use by maintenance electricians, OEM manufacturers, and system integrators on new installations, equipment maintenance, retrofit projects, and replacement of existing conduit hubs, this zinc die-cast hub and locknut features a molded thermoplastic insulating throat rated at 105°C (UL 94 V-0) and a nitrile (BUNA-N) sealing ring to protect conductor insulation from abrasion and moisture ingress. It uses a threaded NPT connection compatible with RMC and IMC in threadless boxes and enclosures, and includes an integrated grounding locknut and a watertight seal to promote corrosion resistance in demanding environments. The hub is suitable for Class I, Division 2; Class II, Division 1 & 2; and Class III locations per NEC/CEC requirements, is UL Listed (File E23018) and CSA Certified, and RoHS3 compliant. Common applications include control panels, switchboards, motor control centers, outdoor enclosures, industrial machinery, and hazardous-location electrical systems. Common replacements include H100GR-TB, H150GR-TB, and H125GRA-TB.
