Southwire L428 Squeeze Box Connector Straight Zinc

Product Description

The SOUTHWIRE L428 is a straight zinc squeeze box connector designed for securing flexible metal conduit or armored cable to electrical enclosures and junction boxes. These connectors use a squeeze-style clamping mechanism that allows for tool-free or minimal-tool installation, creating a secure, code-compliant connection at the box entry point. The zinc construction provides corrosion resistance suitable for standard interior electrical work. Licensed electricians and electrical contractors are the primary installers of this fitting in both residential and light commercial wiring applications.

This connector is suited for use in residential and light commercial electrical installations where flexible conduit or armored cable must terminate cleanly at a metal enclosure. The straight configuration makes it appropriate for direct entries where the conduit runs perpendicular to the box wall. This product is sold as a 3-connector pack, making it practical for service calls and small panel or junction box jobs where multiple connections are needed at once. Compatible part references include Madison Electric L-42-8 and Topaz 158.
