HEATCONTROLLERMARS85397 MARS-85397 Nm Cable Connector

Product Description

The HEATCONTROLLERMARS85397 MARS-85397 is a 3/8 inch non-metallic (NM) cable connector sold in a card of 4 units. This fitting is used to secure and protect NM cable as it enters an electrical enclosure, junction box, or panel. The connector grips the cable sheath to prevent pull-out and provides a clean, code-compliant entry point at the knockout. Electricians and electrical contractors reach for this type of connector on residential and light commercial wiring jobs where NM cable is the standard cable type.

This connector is suited for residential new construction, renovation, and service work wherever 3/8 inch knockout entry points are used with NM cable. It is a common consumable on electrical rough-in jobs, panel installations, and junction box work. The 4-per-card pack format keeps job-site inventory manageable for small to mid-size tasks.
