Crouse-Hinds CRS 11 Steel Threaded Conduit Locknut, 1/2-Inch Trade Size

The Crouse-Hinds CRS 11 Steel Threaded Conduit Locknut is a 1/2-Inch trade size fitting engineered to secure threaded rigid or IMC conduit to boxes, enclosures, and panelboards. Machined from steel for long-term durability, this locknut threads onto conduit hubs and draws tight against the mounting surface to hold conduit connections firmly in place. As a fundamental component in threaded conduit systems, it is a staple for electricians completing commercial, industrial, and residential rough-in work where a dependable mechanical connection to a threaded conduit body is required. The compact 1/2-Inch size makes it well suited for smaller branch-circuit runs, panel feed connections, and device box terminations where a solid, code-compliant grounding path and mechanical lock are essential.

Key Features

  • Trade Size: 1/2-Inch, sized to match standard threaded conduit and conduit hub openings.
  • Durable Construction: Steel body construction provides strength and long service life in threaded conduit assemblies.
  • Threaded Design: Internal threads engage standard threaded conduit for a secure, code-compliant mechanical connection.
  • Simple Installation: Hand- or wrench-tightened onto conduit threads and cinched against the enclosure wall to lock the conduit in position.
  • Versatile Application: Suited for use with boxes, panelboards, and enclosures wherever threaded rigid or IMC conduit terminates.

Crouse-Hinds CRS11 – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds CRS steel conduit locknut come in?
Four trade sizes: 1/2 inch (model 11), 3/4 inch (model 12), 1 inch (model 13), and 2 inch (model 16). Order the locknut to match the conduit trade size, not the box opening, since the nut threads onto the conduit or hub threads.
2) Will a Crouse-Hinds CRS locknut work with EMT, or only rigid and IMC?
These are threaded locknuts for threaded rigid and IMC conduit terminations. EMT is not threaded, so an EMT run needs a set-screw or compression connector instead, and the locknut only comes into play on the threaded body of that connector where one is supplied.
3) Does a conduit locknut like the Crouse-Hinds CRS 11 provide a grounding path, or do I still need a bonding bushing?
The 1/2 inch CRS 11 locknut cinches metal-to-metal against the enclosure wall and is described as providing a solid, code-compliant grounding path and mechanical lock on threaded conduit terminations. Where your installation calls for a bonding jumper or a bonding-type bushing, that is a separate fitting and not part of the locknut.
4) Can I use the Crouse-Hinds CRS locknut on a panelboard entry and a device box on the same job?
Yes. The CRS steel locknuts are used at electrical boxes, enclosures, panelboards, and load center conduit entries, in commercial, industrial, and residential rough-in. For a mixed job, stock the sizes that match your runs: 1/2 and 3/4 inch for branch circuits and device boxes, 1 and 2 inch for larger feeders.
5) How do I install a Crouse-Hinds threaded conduit locknut?
Thread it onto the conduit or hub threads by hand, then run it down and cinch it against the enclosure, box, or panelboard wall with a wrench or screwdriver against the lugs. No other hardware is supplied with the nut.
