Southwire L58 Bx Flex Set Screw Box Connector Zinc

Product Description

The SOUTHWIRE L58 is a zinc set screw box connector designed for use with BX armored cable and flexible metal conduit (FMC). It provides a secure, code-compliant termination point where armored or flexible conduit enters an electrical enclosure or junction box. The set screw fastening method locks the connector firmly onto the conduit, preventing pull-out and maintaining a reliable ground path through the metal assembly. Licensed electricians and electrical contractors install this connector during rough-in and finish wiring stages on both residential and commercial projects.

The L58 connector is suited for applications where BX cable or flexible metal conduit must be terminated at a standard knockout opening on an electrical box or panel enclosure. Its zinc construction provides corrosion resistance appropriate for typical indoor wiring environments. This connector is a direct equivalent to Madison Electric L-58 and Topaz 130TZ, making it a widely recognized replacement option across common electrical supply references.

Compatibility

The L58 is a recognized equivalent to Madison Electric L-58 and Topaz 130TZ. It is designed as an OEM-style replacement connector for standard BX armored cable and flexible metal conduit terminations at electrical box knockouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) requirements for armored cable and flexible metal conduit terminations. De-energize the circuit and verify the absence of voltage before beginning any work at the enclosure. Insert the conduit into the connector body and tighten the set screw to secure the assembly before seating the connector into the box knockout and securing the locknut. Do not overtighten the set screw in a manner that damages the cable jacket or conduit wall.
