Arlington Industries DLN8 Die Cast Locknut 3 Inch

Product Description

The ARLINGTON INDUSTRIES DLN8 is a 3-inch die cast locknut used to secure conduit fittings and connectors to electrical enclosures, junction boxes, and panel knockouts. Die cast construction provides a solid, low-profile connection point that resists loosening under vibration. This locknut is sold as an individual unit and is installed by licensed electricians during conduit rough-in, panel work, and box assembly on both residential and commercial electrical systems.

The DLN8 is suited for standard conduit installation applications where a threaded locknut is required to fasten a connector or fitting into a metal enclosure knockout. It is commonly used in branch circuit wiring, service entrance work, and conduit system assembly where a secure mechanical connection between the fitting and the enclosure is required.

Key Features

• 3-inch size fits standard 3-inch threaded conduit fittings and knockouts
• Die cast construction for solid, durable mechanical connection
• Low-profile design seats flush against enclosure walls
• Sold individually for single-unit replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation locknut for use with standard 3-inch threaded conduit connectors and fittings on metal electrical enclosures and junction boxes.

Installation Notes

Installation is performed by a licensed electrician. De-energize the panel or enclosure and verify absence of voltage before beginning work. Thread the locknut onto the conduit connector or fitting, insert through the enclosure knockout, and tighten securely using a locknut wrench or screwdriver seated in the lugs. Installation should comply with applicable NEC requirements for conduit system assembly and enclosure entry.
