Overview

The NSi Industries 164-DCG 1-1/4" Threaded Grounding and Bonding Hub is a zinc or copper-free aluminum component designed for reliable electrical grounding and bonding in industrial and commercial applications. Engineered with a threaded connection type, it ensures secure, leak-free installations while maintaining electrical continuity. The hub features a thermoplastic insulating throat rated for 105°C with a UL94-V0 flammability rating, providing thermal and fire safety compliance. A nitrile (BUNA "N") sealing ring delivers a 360° seal, even when conduit isn’t perpendicular to the enclosure, preventing moisture and dust ingress. The hexagonal/splined body and locknut enable fast, tool-assisted installation, while the PVC-coated exterior offers corrosion resistance in harsh environments. Certified to NEMA 3R, 4, and 13 enclosure standards, this hub meets UL and CSA requirements, including hazardous location classifications (Class II Groups E.F.G. and Class III). Ideal for electrical systems, telecommunications, and infrastructure projects, the 164-DCG ensures long-term reliability and operational safety.
