Eaton UNJC232 Flexible Fixture Hanger - Cushion Type
Part Number: UNJC232
Quick Summary
The Eaton UNJC232 flexible fixture hanger is designed to support hazardous-area luminaires in industrial facilities. When installations occur in tight ceilings or congested runs, electricians struggle with alignment and vibration-induced wear. This solution aligns with UL listings for Ball or Cushion Hazardous Area Flexible Fixture Hangers and NEC/CEC standards, including a Class I, Division 2 rating for hazardous locations. The pendant-mount design, combined with a 3/4" luminaire stem and malleable-iron construction, delivers reliable, code-compliant support while reducing downtime and inventory complexity. For projects that demand rugged, compliant mounting with straightforward installation, UNJC232 pairs well with standard luminaires and supports 24-48 lb fixtures.

FAQs
UNJC232 is designed for pendant mounting with a 3/4 in luminaire stem, supporting up to 24-48 lb luminaires. For high-ceiling work, verify support structures are rated for the load, use the provided nipple sizing, and ensure the fixture is secured with appropriate hanger hardware. The cushion design helps absorb vibration and reduces dynamic stress during long runs, improving alignment stability over time.
The Class I, Division 2 rating indicates suitability for hazardous locations where flammable gases or vapors may be present under abnormal conditions. This rating, alongside NEC/CEC compliance, informs proper selection for industrial environments such as oil, chemical, or mining facilities. Always follow local codes and UL guidance when integrating UNJC232 into hazardous-area luminaires.
Yes. UNJC232 uses a 3/4 in luminaire stem and 3/4 in nipple, aligning with many common luminaires and suspension systems. Its pendant mounting and malleable-iron construction provide robust support for mid-weight fixtures in varied ceiling types, including concrete, steel, and wired-lattice installations, while maintaining flexibility for future retrofits.
UNJC232 is evaluated under NEC/CEC standards with a Class I, Division 2 hazardous-location rating and UL certification references for Ball or Cushion Hazardous Area Flexible Fixture Hangers. Data sheets and certification reports are available through Eaton’s resources and UL’s database, with a dedicated specification sheet (UNJC232) for technical details and compliance notes.
Cushion-type hangers like UNJC232 reduce vibration-induced wear, lowering maintenance cycles and extending luminaire life in harsh environments. The standardized 3/4 in stem/nipple simplifies part sourcing and installation time, which lowers labor costs. In hazardous locations, the improved reliability also reduces downtime and audit-related compliance risk, delivering measurable total-cost-of-ownership savings over fixture life cycles.
