Abb Installation Products spln108 Locknut 3 Inch

Product Description

The ABB INSTALLATION PRODUCTS spln108 is a thin-construction locknut designed to secure rigid metal conduit (RMC) and intermediate metal conduit (IMC) fittings to enclosures, junction boxes, and panel knockouts. Manufactured from steel with a zinc-plated finish, it provides corrosion resistance suited to standard interior and protected exterior electrical installations. The thin profile is useful in tight knockout configurations where a standard-height locknut would interfere with adjacent hardware. At 3 inches, this locknut is sized for large-diameter conduit runs common in commercial and industrial power distribution systems. Licensed electricians and electrical contractors are the primary installers of this hardware.

This locknut is intended for use with 3-inch rigid metal conduit and IMC systems. It is typically installed at panel enclosures, junction boxes, and conduit bodies where a secure, vibration-resistant threaded connection is required. The zinc-plated steel construction makes it appropriate for dry and damp locations as defined by the NEC. Its thin-construction design is particularly useful in high-density conduit entry applications where multiple knockouts are in close proximity.

Key Features

• Thin-construction profile fits tight knockout spacing without interference
• Steel construction with zinc-plated finish for corrosion resistance
• Sized for 3-inch rigid metal conduit and IMC
• Listed under UL E23018
• Compatible with standard threaded RMC and IMC fittings

Compatibility

Designed for use with 3-inch rigid metal conduit and intermediate metal conduit (IMC) systems. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by licensed electricians in accordance with applicable NEC requirements. Power must be de-energized and locked out before working inside any enclosure or panel where this locknut is being installed. Use an appropriate spanner wrench or locknut wrench to achieve proper engagement on the threaded conduit fitting without distorting the thin-profile body. Ensure the conduit fitting is fully seated and the locknut is tightened until the teeth bite into the enclosure wall for a secure, bonding-quality connection.
