Appleton 30-350 Malleable Iron Compression Conduit Coupling

Product Description

The APPLETON 30-350 is a 3.5-inch malleable iron compression conduit coupling designed for joining conduit sections in electrical raceway systems. This fitting creates a secure mechanical connection without threading, using a compression-style engagement that holds conduit firmly in place. Malleable iron construction provides durability in demanding commercial and industrial environments. Licensed electricians and electrical contractors install this fitting during conduit rough-in on new construction and retrofit projects where a reliable, code-compliant connection is required.

This coupling is suited for use in commercial and industrial electrical installations where 3.5-inch conduit runs are specified. It is appropriate for interior and exterior applications where malleable iron fittings meet the job specification. The compression design allows for efficient installation on standard conduit without specialized threading equipment, making it a practical choice for high-volume raceway work.

Key Features

• 3.5-inch trade size fits standard conduit of matching diameter
• Malleable iron construction resists mechanical stress and impact
• Compression-style connection eliminates the need for threaded conduit ends
• Suitable for commercial and industrial electrical raceway applications
• Compact form factor supports installation in tight conduit runs

Compatibility

Designed as an OEM-style compression coupling for use with 3.5-inch trade size conduit in commercial and industrial electrical raceway systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out all circuits before working on any conduit system. Ensure conduit ends are clean, burr-free, and fully seated before tightening the compression fitting. Do not over-tighten, as malleable iron fittings can crack under excessive torque applied with power tools.
