The NESCO 1" Aluminum Locknut is a go-to fitting for electricians securing conduit connectors at knockout openings in panels, junction boxes, and enclosures across residential, commercial, and industrial job sites. Its lightweight aluminum construction delivers a tight, vibration-resistant connection while resisting the corrosion that can compromise long-term electrical continuity and grounding. It threads on fast and seats flush for a clean, code-compliant finish.
