Thomas & Betts HA-203 Chase Nipple For 1-Inch Rigid Metal Conduit

Description:

The Thomas & Betts HA-203 Chase Nipple is used to provide a secure threaded connection through electrical enclosure knockouts for 1-inch rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems. Commonly installed in junction boxes, panelboards, switchgear, control panels, and commercial or industrial electrical installations where conduit must be terminated through a knockout while maintaining mechanical continuity. Maintenance electricians, electrical contractors, OEM manufacturers, and system integrators use this chase nipple for new installations, equipment upgrades, maintenance, and replacement of existing conduit fittings.

Applications:

The Thomas & Betts HA-203 is designed to terminate 1-inch rigid metal conduit or IMC into electrical boxes and enclosures using a locknut connection. Its zinc die-cast construction provides excellent corrosion resistance and mechanical strength, while the male NPT thread and hex-head design simplify installation. The chase nipple is ideal for electrical distribution equipment, industrial machinery, switchboards, commercial buildings, and OEM electrical assemblies requiring a durable conduit-to-enclosure connection.
