Halex/scott Fetzer 90440 Screw in Connector 3/8 Inch Fmc

Product Description

The HALEX/SCOTT FETZER 90440 is a 3/8 inch screw-in connector designed for terminating armored cable (AC) and flexible metallic conduit (FMC) into a 1/2 inch knockout. Constructed from die cast zinc, this connector provides a secure mechanical connection between flexible raceway or cable armor and an enclosure wall. It installs by threading directly into the knockout opening without the need for a locknut on the exterior, simplifying the termination process. Packaged in a 25-piece polybag, it is suited for jobs requiring multiple connections on panels, boxes, or fixtures.

This connector is used in residential and light commercial electrical installations wherever armored cable or flexible metallic conduit must be secured to an enclosure. Typical applications include connections to load centers, junction boxes, and electrical panels. The 3/8 inch trade size accommodates the corresponding armor or conduit diameter, while the 1/2 inch knockout fit is one of the most common enclosure opening sizes encountered in the field. Electricians reach for this connector on new construction and retrofit work alike.

De-energize and lock out the circuit or panel before making any connections. Thread the connector into the knockout until snug and verify the cable or conduit is fully seated and secured by the connector before restoring power.
