Southwire L107 Non-watertight Zinc Conduit Connector

Product Description

The SOUTHWIRE L107 is a non-watertight zinc conduit connector designed for use with 1-1/2 inch Romex-style cable entries in electrical enclosures and junction boxes. Constructed from zinc for durability and corrosion resistance in standard indoor applications, this connector secures non-metallic sheathed cable to boxes, panels, and conduit fittings without requiring a watertight seal. It is installed by licensed electricians and experienced electrical tradespeople during rough-in and finish wiring on residential and light commercial projects. The L107 ships in a multi-piece package and is a direct equivalent to Topaz 955, Madison L-107, and Topaz 145R.

This connector is suited for residential and light commercial electrical installations where a non-watertight cable connection is acceptable per applicable code. Typical applications include securing NM-B cable runs into metal boxes, load centers, and enclosures in dry or protected locations. It is commonly used during new construction and retrofit wiring projects where consistent, repeatable connections are required across multiple termination points.
