Thomas & Betts HA-407 Conduit Nipple

Description:

The Thomas & Betts HA-407 Conduit Nipple is used to provide a secure threaded connection between 2-1/2-inch rigid metal conduit (RMC) or intermediate metal conduit (IMC) and electrical enclosures. Commonly installed in junction boxes, panelboards, switchgear, control panels, and commercial or industrial electrical systems where conduit must terminate 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.

The Thomas & Betts HA-407 is designed to connect 2-1/2-inch rigid metal conduit or IMC to electrical boxes, fixture housings, or adjacent enclosures using locknuts or conduit couplings. Its zinc-plated malleable iron construction provides excellent strength and corrosion resistance, while the male NPT threaded design ensures a secure mechanical connection. The chase nipple is widely used in commercial buildings, industrial facilities, OEM equipment, switchboards, and electrical distribution systems requiring dependable conduit termination.
