Southwire 860 4 Inch 3-piece Conduit Coupling

Product Description

The SOUTHWIRE 860 is a 4-inch, 3-piece conduit coupling designed for joining conduit sections in electrical raceway installations. The 3-piece construction allows technicians to make connections without rotating the conduit, which is a practical advantage in tight or fixed-run situations. At 13 pounds, this is a heavy-duty fitting built for robust conduit systems. Licensed electricians and electrical contractors install this type of coupling on rigid metal conduit or IMC runs where a secure, code-compliant mechanical joint is required.

This coupling is suited for commercial and industrial electrical installations where 4-inch conduit is routed through walls, ceilings, or exposed structural areas. The 3-piece design is particularly useful in retrofit or repair scenarios where existing conduit cannot be freely turned. It is a standard fitting in larger electrical distribution systems, service entrances, and feeder runs requiring 4-inch raceway.

Key Features

• 4-inch trade size fits standard 4-inch rigid or IMC conduit
• 3-piece design allows coupling without rotating conduit runs
• Heavy-duty construction rated for commercial and industrial applications
• Supports code-compliant conduit raceway assembly per NEC requirements

Compatibility

Designed as an OEM-style replacement and standard fitment coupling for 4-inch rigid metal conduit and intermediate metal conduit raceway systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local electrical codes. De-energize all circuits in the conduit run before beginning any raceway work. Use appropriate pipe wrenches or conduit tools to thread and tighten the coupling components evenly. Inspect conduit threads for damage before assembly to ensure a secure mechanical connection.
