Appleton 29-150 Malleable Iron Conduit Coupling 1-1/2 in

Product Description

The APPLETON 29-150 is a 1-1/2 inch malleable iron set screw conduit coupling designed for joining sections of rigid metal conduit or intermediate metal conduit in electrical raceway systems. This coupling provides a secure mechanical connection between conduit runs and is installed by licensed electricians during new construction or retrofit wiring projects. The set screw design allows for tool-assisted tightening without threading the conduit ends together, speeding up assembly on the job site. At 1 pound, it is a compact and durable fitting suited for standard trade use.

This coupling is used in commercial and residential electrical installations where rigid or IMC conduit systems require a reliable mechanical joint. It is well suited for exposed conduit runs in industrial facilities, utility rooms, mechanical spaces, and similar environments where conduit protection and raceway integrity are required by NEC guidelines.

Key Features

• 1-1/2 inch trade size for use with matching conduit diameter
• Malleable iron construction for durability in demanding installation environments
• Set screw fastening method for secure, tool-tightened connection without conduit threading
• Compact profile at 0.75 inches height to fit tight conduit routing conditions
• Suitable for rigid metal conduit and intermediate metal conduit applications

Compatibility

Designed as an OEM-style replacement fitting for 1-1/2 inch rigid metal conduit and intermediate metal conduit raceway systems in commercial and residential electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the affected raceway before beginning conduit work. Use a proper set screw driver or hex key to tighten the set screws to a firm, secure fit without stripping. Inspect conduit ends for burrs or damage before inserting into the coupling to ensure a clean, continuous raceway.
