Appleton 4-125 Malleable Iron 3-piece Conduit Coupling

Product Description

The APPLETON 4-125 is a 1-1/4 inch malleable iron three-piece conduit coupling designed for joining conduit sections in electrical raceway installations. Malleable iron construction provides the toughness needed in industrial and commercial environments where rigid metal conduit systems are exposed to mechanical stress or vibration. The three-piece design allows the coupling to be installed without rotating the conduit, making it practical for field connections where one or both conduit runs are fixed in place. Licensed electricians and electrical contractors install this fitting as part of a complete rigid or IMC conduit system.

This coupling is suited for use in commercial, industrial, and heavy-duty residential electrical installations where rigid metal conduit or intermediate metal conduit is specified. The three-piece construction is especially useful in retrofit or repair work where conduit cannot be freely spun. It is a standard trade fitting stocked by electrical supply houses and carried by journeymen electricians working on conduit runs in exposed or concealed raceway systems.

Key Features

• 1-1/4 inch trade size fits standard rigid metal conduit and IMC of the same size
• Three-piece design allows installation without rotating conduit
• Malleable iron construction resists mechanical stress and impact
• Compact profile suitable for tight conduit runs

Compatibility

Designed as an OEM-style replacement fitting for 1-1/4 inch rigid metal conduit and intermediate metal conduit installations in commercial and industrial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for rigid metal conduit systems. De-energize all circuits in the work area before beginning conduit work. Ensure conduit ends are properly reamed and deburred before threading into the coupling. Do not overtighten the coupling halves unevenly, as this may compromise the mechanical integrity of the assembly.
