Nsi Industries GHM-75 Swing Conduit Hub 3/4 Inch Bronze

Product Description

The NSI INDUSTRIES GHM-75 is a 360-degree swing type conduit hub designed to ground copper grounding conductors to water pipes in indoor environments. Built from bronze with zinc-plated steel screws, this hub accepts 3/4 inch conduit or wire ranging from 10 SOL to 2/0 STR. The full 360-degree rotation allows the hub to accept entry from any direction, simplifying alignment during installation. It is intended for use with NSI ground clamps that feature serrated hubs. Licensed electricians install this fitting as part of grounding electrode conductor systems in residential and commercial applications.

The GHM-75 is suited for indoor grounding installations where a rigid metal conduit or wire entry point must be aligned to a water pipe clamp assembly. The 360-degree swing eliminates the need to reposition the pipe clamp or reroute conduit to achieve a straight entry angle, making it especially useful in tight mechanical rooms or panel rooms where conduit routing options are limited. The 3/4 inch hub size accommodates a broad range of conductor sizes from 10 SOL to 2/0 STR.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for grounding electrode conductor fittings. De-energize the circuit and verify power is off before handling any conductors or making connections.
