Industrial NSB AX-400 EMT Elbow Coupling Joint

The NSB AX-400 EMT Elbow Coupling Joint is a steel EMT fitting that creates a 90-degree, right-angle bend between two sections of Electrical Metallic Tubing in a 4-inch nominal size. Manufactured by SteelElectric Products, the AX-400 is offered as a single unit (EA) and is specified for use with standard 4-inch EMT conduit in industrial and commercial installations. It provides a rigid, secure connection between conduit runs, allowing clean routing around obstacles and along walls or ceilings. Typical applications include electrical distribution in factories, warehouses, data centers, and office buildings where EMT conduit must navigate corners or transitions. When installing, follow applicable electrical codes and manufacturer guidelines to ensure proper alignment, spacing, and support for the EMT run.
