Conduit locknut is a threaded, ring-shaped fitting that secures a conduit connector or hub to an enclosure’s knockout. It is threaded onto the connector from inside (or sometimes outside) the enclosure. When tightened, it clamps securely against the enclosure wall, ensuring a mechanical connection and electrical grounding continuity.
