About the Twin-Screw Clamp Connector

Standard twin-screw NM cable connector for transitioning non-metallic sheathed cable or flexible cord into a steel junction box, panel, or metal enclosure. The clamp secures the cable sheath so the conductors inside aren't supporting their own weight or subject to pull-out, and the connector body threads into a standard knockout.

Reversible Grounding Locknut

The included locknut is reversible with a toothed face that bites through paint, powder coat, or other protective coatings on the enclosure to establish a solid ground path. This maintains ground continuity without having to scrape the coating off the knockout area manually.

Trade Sizes

The 3/8" connector fits a standard 1/2" knockout and handles typical 14/2 and 12/2 NM-B cable. The 3/4", 1", and 1-1/4" sizes accommodate progressively larger cable runs and higher conductor counts. Match the trade size to your cable diameter and the knockout size on your enclosure.
