Halex/scott Fetzer 90451 1/2 Inch Screw in Coupling 25 Pack

Product Description

The HALEX/SCOTT FETZER 90451 is a 1/2 inch screw-in coupling designed for connecting armored cable (AC) and flexible metal conduit (FMC) to electrical boxes and enclosures. Constructed from die cast zinc, this coupling provides a secure, corrosion-resistant mechanical connection in standard residential and light commercial electrical installations. Each unit is sold in a package quantity of 25, making it a practical choice for contractors and electricians stocking up for multiple runs or larger projects. Installation is straightforward, using the threaded screw-in design to engage the conduit and secure the fitting at the box knockout.

This coupling is suited for use with 1/2 inch armored cable and 1/2 inch flexible metal conduit in branch circuit wiring applications. Typical install scenarios include residential panel work, device box connections, and light commercial rough-in where AC or FMC terminations are required at enclosure knockouts. The 25-unit polybag packaging keeps inventory organized on the job site and is UPC-coded for easy tracking.

Installation Notes

Installation is performed by licensed electricians in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before working at any enclosure. Thread the coupling into the knockout by hand, then tighten securely to maintain the required mechanical and electrical continuity of the raceway system. Do not overtighten, as die cast zinc fittings can crack under excessive torque.
