Eaton UNJ2 Flexible Fixture Hanger - Ball, Class I Div 2

Durable malleable iron construction provides a robust, vibration-resistant mounting platform for hazardous-area luminaires used in chemical plants, refineries, and heavy manufacturing. The UNJ2 is rated to support fixtures up to 125 lb, reducing the risk of sag, disengagement, or unexpected drops in demanding environments where equipment vibrations and thermal cycling are common. This rugged build translates into fewer field service calls, lower spare-parts consumption, and predictable maintenance budgets for critical lighting during plant start-ups and routine operations alike. With a pendant mounting type and a 3/4 inch luminaire stem paired to a 3/4 inch nipple, installation is straightforward in existing conduits and new builds. The ball-type design enables quick orientation and fine-tuning of fixture tilt and heading without rework, cutting commissioning time and improving lighting uniformity along production lines. In retrofit projects, the UNJ2’s compact footprint minimizes ceiling space conflicts while preserving accessibility to quick-disconnect electrical connections. Compliance is built in: NEC/CEC standards and UL certifications accompany the UNJ2, confirming suitability for Class I Division 2 hazardous locations and providing traceable safety documentation for risk assessments. This minimizes design and audit risk for oil and gas facilities, chemical plants, and mining support sites where code adherence is mandatory. Contractors appreciate reliable product documentation, consistent performance, and reduced QA checks when sourcing recognized suspension components from trusted brands. Physical footprint matters in crowded ceilings: at 4.95 inches in length, 0.99 inches in height, and 3.83 inches in width, the UNJ2 fits tight plenums and aligns with standard 3/4 inch hardware. The lumen-weight balance and mounting geometry streamline maintenance and replacement tasks while keeping luminaire weight within safe limits. Beyond installation, the UNJ2 integrates with Eaton Crouse-Hinds accessories, enabling scalable retrofits as lighting needs evolve. The combination delivers project predictability, faster upgrade cycles, and safer, code-compliant installations across facilities.
