Product Description

The HALEX/SCOTT FETZER 05103B is a 3/8 inch twin screw clamp connector designed to terminate Type NM cable to a knockout opening in a dry location electrical box or enclosure. Constructed from die cast zinc, this connector provides a secure, code-compliant cable entry point. The twin screw clamping design locks NM cable firmly in place, reducing movement and strain at the termination point. This 100-pack contractor quantity is sized for volume electrical work on residential and light commercial projects. Both UL and CSA listing confirm the connector meets established safety standards for electrical installations.

This connector is suited for residential and light commercial electrical rough-in work where Type NM cable must be secured at panel boxes, junction boxes, or other dry location enclosures. The 3/8 inch trade size fits standard knockout openings commonly found in steel and plastic enclosures. Electricians and electrical contractors use this connector during new construction and retrofit wiring jobs. The contractor pack of 100 units supports multi-unit or multi-room installations without repeated restocking.
