3/4" Rigid Steel Locknut

The Southwire 282 is a 3/4 inch rigid steel locknut engineered to connect externally threaded conduit or connectors to threadless openings in electrical boxes and enclosures. This zinc-plated steel locknut provides a secure, code-compliant connection for rigid and IMC conduit systems in commercial and residential electrical installations. Built with OPD (Oversized Pipe Diameter) threads, it ensures a tight, reliable fit that electricians and contractors trust for lasting performance.

• Zinc-Plated Steel Construction: Manufactured from zinc-plated steel, this locknut resists corrosion and wear in indoor and outdoor installations. The durable plating extends service life and maintains secure connections even in demanding environments.
• OPD Thread Design: Features OPD (Oversized Pipe Diameter) threads that accommodate the actual outer diameter of rigid and IMC conduit. This thread design ensures proper engagement and a tight, vibration-resistant connection every time.
• 3/4 Inch Trade Size: Sized for 3/4 inch rigid and IMC conduit, the locknut matches standard trade sizing used across the electrical industry. This standardization simplifies ordering and guarantees compatibility with common conduit runs.
• Threadless Box Connection: Designed to connect externally threaded conduit or connectors to threadless knockouts in boxes and enclosures. This versatile function streamlines installation and eliminates the need for additional adapters or hardware.
• Code-Compliant Application: Suitable for use in rigid and IMC conduit systems that meet National Electrical Code requirements. Using the correct locknut supports compliant installations and passes inspection.

The Southwire 282 locknut is compatible with 3/4 inch rigid steel conduit and 3/4 inch IMC (Intermediate Metal Conduit). It threads onto externally threaded conduit ends or connectors and secures them into threadless openings found in standard electrical boxes, enclosures, and junction boxes. The OPD thread design matches the true outside diameter of rigid and IMC conduit for proper engagement.
