Appleton 2-400 Malleable Iron Bushing 4 Inch

Product Description

The APPLETON 2-400 is a 4-inch malleable iron bushing used in conduit systems to reduce or protect conductors at the end of a conduit run. Malleable iron construction provides durability in demanding electrical installations where standard plastic or zinc fittings are not suitable. This bushing is installed by licensed electricians working on commercial, industrial, and heavy-duty residential conduit runs where robust, code-compliant fittings are required.

The 2-400 bushing fits 4-inch conduit terminations and is a standard component in rigid metal conduit and intermediate metal conduit systems. It is commonly used at panel entries, junction boxes, and conduit bodies to protect wire insulation from sharp conduit edges. This fitting suits installations in industrial plants, commercial buildings, and utility applications where malleable iron fittings are specified.

Key Features

• 4-inch size fits standard rigid and intermediate metal conduit
• Malleable iron construction for strength and impact resistance
• Protects conductor insulation at conduit termination points
• Suitable for heavy-duty commercial and industrial conduit installations

Compatibility

Designed as an OEM-style replacement fitting for 4-inch rigid metal conduit and intermediate metal conduit termination applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit fittings and conductor protection. De-energize all circuits and lock out the panel before working on conduit terminations. Standard conduit threading tools and wrenches are used to seat the bushing securely at the conduit end. Inspect the bushing seating surface to confirm conductors are fully protected before restoring power.
