The Conversions Tech Rigid Steel Locknut with Zinc Plated 3" is a heavy-duty fastening component designed to secure 3-inch rigid steel conduit to electrical boxes, junction boxes, and conduit fittings. This locknut is particularly used in larger electrical systems and industrial applications where large conduit sizes are required for routing electrical wiring. The zinc-plated finish provides excellent resistance to corrosion, making it suitable for use in both indoor and outdoor environments, particularly in applications exposed to moisture, chemicals, or other harsh conditions.


Product Description:

The Rigid Steel Locknut with Zinc Plated 3" is designed to provide a secure and stable connection between rigid steel conduit and electrical enclosures. This locknut features internal threads that securely attach to 3-inch rigid steel conduit, holding it tightly in place against electrical boxes, junction boxes, or conduit fittings. The 3-inch size is typically used in larger conduit systems that require robust, reliable connections for heavy-duty electrical wiring.

The zinc-plated finish enhances the locknut's resistance to corrosion and rust, making it an ideal choice for installations in outdoor or corrosive environments. The locknut is easy to install by hand, making it an efficient choice for electricians working on large conduit systems without the need for special tools. It is UL Listed and compliant with National Electrical Code (NEC) standards, ensuring safety and reliability in electrical installations.


Specifications:

  • Size: 3 inches (for 3" rigid steel conduit)
  • Material: Steel (with zinc-plated finish for enhanced corrosion resistance)
  • Thread Type: Internal threads for secure attachment to the conduit and fittings
  • Finish: Zinc plating (provides corrosion protection)
  • Application: Secures 3" rigid steel conduit to electrical boxes, junction boxes, and fittings
  • Code Compliance: UL Listed and compliant with NEC (National Electrical Code) standards
  • Packaging: Available in bulk or individual units depending on the supplier

Cases & Uses:

  1. Rigid Conduit to Electrical Box Connections: Primarily used to secure 3" rigid steel conduit to electrical boxes, junction boxes, or enclosures, ensuring a tight and stable connection.
