Appleton 28-050 Malleable Iron Set Screw Conduit Connector

Product Description

The APPLETON 28-050 is a 1/2 inch malleable iron set screw conduit connector used to secure rigid metal conduit or EMT to electrical enclosures, junction boxes, and panel knockouts. The set screw design allows for fast, tool-simple termination without threading, making it a common choice for licensed electricians running conduit in commercial and residential electrical installations. Malleable iron construction provides the mechanical strength and corrosion resistance required in standard indoor and light-duty industrial environments.

This connector is suited for use in branch circuit conduit runs, panel feeders, and junction box connections where a reliable, code-compliant termination is required. It is a standard trade-size 1/2 inch fitting appropriate for 1/2 inch conduit systems in new construction and retrofit work. Electricians and electrical contractors install this fitting during rough-in and finish stages of electrical work.

Key Features

• 1/2 inch trade size fits standard 1/2 inch rigid or EMT conduit
• Malleable iron body for strong, durable mechanical connection
• Set screw fastening for fast installation without threading
• Compatible with standard electrical enclosure knockouts
• Suitable for indoor and light-duty industrial conduit applications

Compatibility

Designed as an OEM-style replacement and standard trade fitting for 1/2 inch conduit termination at electrical enclosures and junction boxes.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements for conduit support and termination. Power down the circuit and verify zero voltage at the enclosure before opening or modifying any conduit connection. Insert the conduit fully into the connector body before tightening the set screw with a flathead screwdriver or hex key. Do not overtighten the set screw, as this can deform the conduit wall and compromise the mechanical connection.
