Thomas & Betts 4240 Insulated Short Conduit Elbow

Description:

The Thomas & Betts 4240 Insulated Short Elbow is used to provide a compact 90-degree transition for 1/2-inch Electrical Metallic Tubing (EMT) in confined electrical installations. Commonly installed in control panels, switchgear, commercial buildings, industrial facilities, and OEM equipment, this malleable iron elbow features a thermoplastic insulated throat that protects conductors from abrasion while maintaining a secure conduit connection. Maintenance teams and system integrators use this fitting for repair, retrofit, expansion, and replacement of EMT conduit systems.

Applications:

The Thomas & Betts 4240 is designed to connect 1/2-inch EMT conduit where space is limited and a standard-radius elbow cannot be installed. It is ideal for electrical enclosures, junction boxes, panelboards, motor control centers, and industrial conduit systems requiring a compact, UL-listed, and CSA-certified 90-degree conduit fitting with conductor protection.
