Throat Bushing System Benefits

Throat bushings provide essential conductor protection that bare conduit terminations cannot offer. The insulated design prevents wire insulation damage during installation and service, reducing the risk of ground faults and electrical failures. This protection is especially critical in commercial and industrial applications where wire replacement costs and downtime can be substantial. The threaded design ensures the bushing remains securely in place throughout the system's service life.

Why Choose Malleable Iron Construction?

Malleable iron offers superior mechanical properties compared to standard steel fittings, providing enhanced impact resistance and dimensional stability under mechanical stress. This material choice ensures the throat bushing maintains its protective function even in demanding industrial environments. Combined with Eaton Crouse-Hinds' century of electrical innovation, this throat bushing delivers the reliability and performance that electrical professionals demand for critical conductor protection applications.
