Southwire LB10M Type Lb Conduit Body 4 Inches

Product Description

The SOUTHWIRE LB10M is a 4-inch malleable iron rigid threaded Type LB conduit body designed for use in electrical conduit systems where a 90-degree change of direction is required. This conduit body allows conductors to be pulled, spliced, or redirected with a removable cover plate for access. Built from malleable iron, the LB10M offers durability and resistance to mechanical stress in demanding installation environments. Licensed electricians and electrical contractors install this fitting as part of rigid metal conduit (RMC) or intermediate metal conduit (IMC) systems in commercial and industrial applications.

The LB10M is suited for commercial and industrial electrical installations where rigid threaded conduit systems require a back-entry, left-exit (LB) configuration. The 4-inch size accommodates large conductor loads and high-capacity feeder runs. It is appropriate for exposed conduit work in factories, utility rooms, and similar service environments. This fitting also cross-references as a replacement for Madison LBM-400 and Topaz LBM10M conduit bodies, making it a direct substitute option for sourcing purposes.

Key Features

• Malleable iron construction provides high mechanical strength and impact resistance
• Rigid threaded connections compatible with standard RMC and IMC threaded fittings
• Type LB configuration allows 90-degree direction change with back-entry and left-exit
• 4-inch trade size accommodates large conductor bundles and feeder-level wiring
• Removable cover plate allows conductor access for pulling and splicing
• Cross-references Madison LBM-400 and Topaz LBM10M for direct replacement sourcing

Compatibility

Compatible with 4-inch rigid metal conduit (RMC) and intermediate metal conduit (IMC) threaded systems. Listed as a direct replacement alternative for Madison LBM-400 and Topaz LBM10M conduit bodies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit body fill and conductor support. De-energize all circuits completely before opening or working near any conduit body. Use appropriate pipe wrenches and thread sealant rated for electrical conduit fittings when making threaded connections. Ensure the cover plate is secured and all conductors remain within allowable fill limits per NEC Article 314.
