The ABB INSTALLATION PRODUCTS FLN38-2 is a 3/8-inch steel fixture locknut sold in a 2-pack. Fixture locknuts are used in electrical conduit and fixture installations to secure fittings, bushings, and connectors to enclosures, boxes, or fixture canopies. Made from steel for reliable holding strength in standard wiring applications, this locknut is a staple fastener for electrical rough-in and fixture hanging work. The FLN38-2 is packaged in a UPC polybag, keeping the pair together for jobsite convenience. Licensed electricians and electrical contractors are the primary installers for this type of hardware.
This fixture locknut is suited for residential and light commercial electrical installations where 3/8-inch threaded conduit fittings or fixture stems need to be locked in place against an enclosure wall or canopy. It is commonly used when mounting ceiling fixtures, junction boxes, and conduit connectors. The 2-pack format is practical for single-fixture jobs or low-quantity service calls.
Designed as an OEM-style replacement and standard-use locknut for 3/8-inch threaded electrical fittings in residential and light commercial conduit and fixture installations.
Installation is typically performed by a licensed electrician. Always de-energize the circuit and verify power is off at the breaker before working on any fixture or enclosure connection. Locknuts should be tightened firmly by hand and then set with pliers or a strap wrench to ensure a secure, low-resistance connection between the fitting and the enclosure. Follow applicable NEC requirements for conduit fitting installation and box fill.
