1/2" PUSH IN CONN

ARL-NM74 (Product Description)

The ARL-NM74 is a 1/2-inch snap-in non-metallic cable connector used to secure NM-B (Romex-type) cable where it enters an electrical box or enclosure.

Product Description

This is a non-metallic sheathed cable connector (Romex connector) designed for quick, tool-less installation into a standard 1/2" knockout. It is used to clamp NM cable securely as it enters a box, providing strain relief and protection so the cable jacket and internal conductors are not damaged.

The “ARL” prefix indicates it is manufactured by Arlington Industries, and the NM74 model is a snap-in style connector, meaning it installs by pushing directly into the knockout without a locknut in many applications.
