3/4" PLASTIC NM CABLE CONN (Product Description)

A 3/4-inch plastic non-metallic (NM) cable connector is a wire clamp fitting used to secure non-metallic sheathed cable (Romex® type) as it enters an electrical box, panel, or enclosure.

Product Description

This is a 3/4" NM cable connector made of plastic (non-metallic) used to safely clamp and protect NM-B electrical cable (typically Romex) where it enters a junction box or device box.

Its main purpose is to:

• Hold the cable securely in place (strain relief)
• Prevent the cable from being pulled or damaged at the box entry
• Protect insulation from sharp metal edges in the knockout opening

The cable is tightened inside the connector using a clamp or snap-in grip mechanism, depending on the design.
