Appleton 4-300 Malleable Iron 3-piece Conduit Coupling 3 in

Product Description

The APPLETON 4-300 is a 3-inch trade size, three-piece malleable iron conduit coupling designed for rigid metal conduit (RMC) and intermediate metal conduit (IMC) installations. This style of coupling allows electricians to join conduit runs where one or both conduit ends cannot be rotated, making it well suited for in-place repairs and tight-quarters work. The malleable iron construction provides reliable mechanical strength and durability in demanding industrial and commercial environments. At 4.370 pounds, the fitting is substantial and built to withstand the physical stresses common in conduit systems exposed to vibration or rough service conditions.

The APPLETON 4-300 three-piece conduit coupling is used in commercial and industrial electrical installations where rigid or intermediate metal conduit runs require coupling without full rotation of the conduit. Typical applications include exposed conduit systems in manufacturing facilities, utility plants, refineries, and heavy commercial construction. The three-piece design addresses scenarios where conduit sections are already fixed in position and a standard coupling cannot be threaded onto both ends simultaneously. Licensed electricians and electrical contractors install this type of fitting as part of NEC-compliant conduit systems.

Key Features

• Three-piece design allows coupling of fixed conduit ends without rotating either conduit section
• Malleable iron construction delivers high mechanical strength and impact resistance
• 3-inch trade size accommodates standard RMC and IMC conduit of matching trade diameter
• Substantial 4.370-pound fitting weight reflects heavy-duty industrial-grade construction
• Suitable for use in demanding commercial and industrial electrical conduit systems

Compatibility

Designed as an OEM-style fitting for use with 3-inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems in commercial and industrial 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 work area before beginning conduit work. Ensure conduit threads are clean and properly cut before assembly; apply an appropriate thread lubricant or sealant as required by the installation environment. Do not over-torque the coupling components, as malleable iron fittings can crack if excessive force is applied.
