CALBRITE 3-inch Stainless Steel Hub

The CALBRITE S63000LT00 is a 3-inch threaded conduit hub constructed from 316 stainless steel. It is designed for connecting rigid metal conduit (RMC) or intermediate metal conduit (IMC) in electrical raceway systems. The fitting carries a UL listing and includes a stainless steel locknut for secure attachment. Suitable for indoor and outdoor installations where corrosion resistance is required.

Threaded NPT Connection with Insulated Throat

Installation uses a standard 3-inch NPT thread to join threaded metallic conduit. The insulated throat helps protect conductor insulation from damage during wire pulling. The polished finish eases thread engagement and reduces galling on stainless threads. Ensure the locknut is tightened to the conduit body to maintain grounding continuity and the hub's environmental seal.

For 3-Inch RMC and IMC Raceway Systems

This hub suits electricians and contractors running 3-inch trade size RMC or IMC in corrosive or wet locations. It is not for use with PVC, EMT, flexible metal conduit or other non-threaded raceway types. Buyers needing a hub for a different trade size or a non-insulated throat should select an alternative fitting.
