STEEL LOCKNUT 1/2" | BAG OF 10

SKU: ED-LNS-S050

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

Ground continuity at every box termination is non-negotiable — and this 1/2" steel locknut makes sure it happens. Designed to thread directly onto connectors and conduit fittings, it bites tight against the knockout to create a solid metallic bond that satisfies code from residential roughing to commercial panel work. The cULus listing backs every installation with confidence, and the all-steel construction at 3.35 mm profile holds secure without crowding adjacent hardware. At the 1/2" trade size, it covers the most common conduit run on the job. Keep a full supply in the bag and you'll never stall a termination waiting on a locknut.
