Halex/scott Fetzer 20420 Squeeze Connector 3/8x1/2 in 3 Pack

Product Description

The HALEX/SCOTT FETZER 20420 is a squeeze-style conduit connector sold in a 3-pack, designed to secure armored cable (AC) or flexible metallic conduit (FMC) to an electrical enclosure through a 3/8-inch by 1/2-inch knockout opening. The die cast zinc construction provides corrosion resistance and mechanical durability suitable for typical indoor and protected outdoor electrical installations. The squeeze connector design allows for tool-free or minimal-tool installation, compressing onto the conduit to create a secure mechanical grip without the need for a separate locknut in most applications. Electricians reach for this connector when terminating AC or FMC runs into panels, junction boxes, or device enclosures.

This connector is suited for residential and light commercial electrical work where armored cable or flexible metallic conduit terminates at a 3/8-inch by 1/2-inch knockout. Common install scenarios include branch circuit wiring in wood-frame and commercial construction, equipment connections, and retrofit work in existing panels or junction boxes. The 3-pack quantity is practical for multi-connection jobs or stocking a service van. Each unit is packaged in a UPC polybag for easy inventory and point-of-use access.

Compatibility

Designed for use with armored cable and flexible metallic conduit applications requiring a 3/8-inch by 1/2-inch knockout connector. Consult applicable NEC requirements to confirm suitability for the specific installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit or panel before beginning any termination work. Insert the conduit into the connector body, compress the squeeze fitting to secure, and seat the connector in the knockout opening, ensuring the retaining ring or locknut engages fully. Do not overtighten or deform the connector body, as this may compromise the mechanical connection.
