Appleton 30-300 3 Inch Malleable Iron Conduit Coupling

Product Description

The APPLETON 30-300 is a 3-inch malleable iron compression conduit coupling designed for securing and joining rigid metal conduit runs in electrical installations. Built from malleable iron, this coupling delivers reliable mechanical strength and resistance to the stresses common in commercial and industrial wiring environments. The compression-style design allows for tool-assisted tightening without threading, speeding up conduit assembly on the job. Licensed electricians and electrical contractors rely on this type of fitting when building out conduit systems that require durable, code-compliant connections at standard trade sizes.

This coupling is suited for use in commercial, industrial, and heavy-duty residential electrical installations where 3-inch rigid metal conduit is specified. It is commonly installed in exposed conduit runs, underground raceways, and panel feeder systems where a secure mechanical joint is required. The malleable iron construction makes it appropriate for environments that demand a robust fitting capable of handling vibration and physical stress over time.

Key Features

• 3-inch trade size for use with standard rigid metal conduit
• Malleable iron construction for high mechanical strength and durability
• Compression-style coupling eliminates the need for threaded connections
• Compact profile at 6.2 x 6.2 x 5.4 inches for practical installation in tight conduit runs
• Solid 4.6-pound build supports long-term performance in demanding environments

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for 3-inch rigid metal conduit systems in commercial and industrial electrical applications.

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 conduit run before beginning work. Use appropriate conduit wrenches or compression tools to achieve a secure, uniform fit. Avoid over-tightening, which can crack or deform the fitting body.
