Eaton 1039NI Throat Bushing - NEC/CEC

Rigid/IMC compatibility and a threaded design deliver a secure connection between conduit and enclosure. This reduces the chance of loosening under vibration, improves grounding continuity, and minimizes field rework during panel assembly. In practical terms, technicians save time when wiring enclosures in tight spaces typical of factory automation floors. Non-ins insulated, malleable iron construction provides rugged durability in harsh environments. The material resists impact and wear while maintaining a reliable seal against dust and debris in ordinary locations. For equipment operating in non-hazardous areas, this resilience translates into longer service life and lower replacement frequency. Trade size of 3-1/2 inches ensures compatibility with common knockouts and enclosures. This standard sizing reduces the need for adapters and simplifies inventory management for procurement teams. When used with standard IMC fittings, it accelerates installation timelines across multiple control panels and machines. Compact weight of 0.64 lb supports easier handling and shipping while maintaining robust strength. This helps reduce freight costs and on-site labor during installation. The 1039NI aligns with NEC/CEC requirements, streamlining compliance checks during commissioning and audits. Industry-ready documentation, including Eaton specification sheets and UL certification references, address common objections about traceability and standards. By pairing trusted material with tested compliance, the part reduces risk of non-conforming installations and supports long-term maintenance planning.
