Eaton MHUB9 Conduit Hub - Malleable Iron, 3-1/2 in

The MHUB9 features malleable iron construction, delivering high strength and outstanding corrosion resistance essential in busy electrical environments. This durability translates into fewer field repairs and longer service life, reducing lifecycle costs for end users. The hub is sized for a 3-1/2 inch trade connection, enabling straightforward routing of mid-size conduits in control panels and equipment enclosures, even where mounting space is tight or vibration is a concern. With precise dimensions—length 5.82 in, width 5.11 in, height 3.21 in—this MHUB9 delivers a predictable footprint that streamlines panel layouts and reduces enclosure modification time. Clearances are easier to maintain, which speeds install sequences and minimizes rework. The result is lower labor costs on every job and improved consistency across multiple panels or cabinets. Compliance and safety: NEC/CEC standards alignment supports code-compliant installations in Ordinary/Non-Hazardous locations. This ensures contractors can specify MHUB9 with confidence for non-hazardous zones, avoiding over-specified equipment that adds cost. The Eaton Crouse-Hinds MHUB series is designed to integrate with other conduit hubs and fittings from the same family, delivering compatible components and consistent performance. Compatibility and installation advantages: The MHUB9 is part of the Crouse-Hinds series, with documented CAD drawings and catalog pages available to help engineers plan routes and ensure correct fit. The 3-1/2 inch trade size pairs with standard conduit schedules, reducing the need for adapters. Field teams appreciate the lightweight yet sturdy profile, which simplifies transport and reduces handling risk in crowded electrical rooms. Objections addressed: Some projects fear weight and ease of installation; MHUB9 addresses both with malleable iron that balances strength with manageability and a compact form that fits tight spaces. Costs are mitigated through durability and fewer replacements. In practice, specifiers rely on NEC/CEC compliance and Ordinary Location rating to maintain reliability while controlling project budgets. Industry context: In midstream automation, compliant conduit hubs reduce risk during audits and field changes; using MHUB9 supports standardization across facilities and streamlines procurement by sticking to a single hub family. This reduces the number of SKUs and simplifies maintenance, training, and spare parts management.
