3/4 in Threaded Grounding Hub

The CALBRITE 60700 IMC grounding hub connects 3/4 inch threaded rigid metal or intermediate metal conduit. It is built from 316 stainless steel with a polished finish for corrosion resistance. An insulated throat protects conductors during wire pulling. The fitting includes a stainless steel locknut for secure mounting.

Insulated Throat and Locknut

The insulated throat prevents insulation damage on conductors entering the hub. The supplied stainless steel locknut matches the hub material to maintain corrosion resistance at the connection point. These bundled items eliminate the need to source separate insulating bushings or hardware.

Verify Conduit and Thread Compatibility

Confirm your installation uses 3/4 inch trade size RMC or IMC with 3/4-14 NPT threads. The hub is UL listed for threaded metallic conduit only. Ensure the 1 7/8 inch overall length fits within your enclosure space.

Questions about this item

Will the 316 stainless steel locknut need replacement due to corrosion?

The 316 stainless steel construction resists corrosion in harsh environments, so the included locknut typically lasts the installation life without replacement.

What is the maximum conduit trade size this 3/4 in hub accepts?

This hub is rated for 3/4 in trade size RMC and IMC conduit; larger conduit will not thread onto the 3/4-14 NPT entry.

Does the insulated throat reduce heat buildup during continuous operation?

The insulated throat protects conductor insulation from abrasion; it does not change the hub's thermal dissipation, which follows the conduit system's normal load rating.
