STEEL LOCKNUT 1" | BAG OF 10

SKU: ED-LNS-S100

Underwriter Laboratories conforms to the safety standards in the US and in Canada

Moving up to 1" conduit means more current-carrying capacity — and the locknut securing it needs to be equally dependable. This cULus-listed 1" steel locknut threads firmly onto connectors and conduit fittings to lock down ground continuity at every box entry on commercial and industrial jobs. The solid steel construction resists loosening under vibration and maintains the metallic bond that inspectors expect. At 3.35 mm profile, it seats cleanly at the knockout without interfering with adjacent hardware or cover plates. For electrical contractors running heavier conduit systems, this steel locknut is a straightforward, cULus-backed solution that removes one variable from the inspection checklist.
