Explosion Proof Arm Bracket With Junction Box | 25 Degree Mount | Class 1 Div 1

Product Overview

This explosion proof arm bracket with junction box is designed for mounting LED explosion proof fixtures in hazardous locations. The 25-degree mounting angle supports directional aiming for task or area illumination in classified environments. This bracket is compatible with multiple LED Lighting Supply EXPL series fixtures and is intended for use in environments requiring Class I Division 1 and Division 2, as well as Class II Division 1 and Division 2 protection. Typical installations include chemical processing plants, paint booths, and oil and gas facilities where hazardous vapors or dusts are present.

The integrated junction box simplifies wiring and ensures a sealed, code-compliant connection. The bracket is suitable for both surface and pendant mounting, supporting a range of hazardous location lighting layouts. The compact form factor allows installation in areas with limited space or where precise fixture orientation is required.

Core Performance and Output

This mounting system is engineered to support LED explosion proof fixtures ranging from 100W to 200W, delivering 14,000 to 28,000 lumens per fixture. The 25-degree arm angle provides controlled fixture orientation for targeted illumination. The bracket and junction box assembly is rated for use with fixtures operating at 100-277V, maintaining electrical integrity in hazardous environments.

The structural design accommodates the weight and EPA of compatible EXPL series fixtures without compromising mounting stability. Excessive fixture weight or non-listed models may exceed the bracket's load rating. The bracket is IP67 rated, ensuring protection against dust and water ingress in demanding industrial settings.

Adjustability and Control Options

The 25-degree fixed arm angle is designed for applications requiring consistent directional aiming. This bracket does not provide field-adjustable tilt or pan; fixture orientation is set by the mounting position. The integrated junction box allows for straightforward wiring and supports standard hazardous location conduit connections.

Control options such as dimming or occupancy sensors are determined by the fixture, not the bracket. The bracket supports both surface and pendant mounting, enabling flexibility in installation layout within hazardous classified spaces.

Longevity and Reliability

The bracket and junction box assembly is constructed from corrosion-resistant materials suitable for harsh industrial and marine environments. The IP67 rating ensures long-term resistance to dust, water, and chemical exposure. All components are designed for continuous operation in hazardous locations without degradation of performance.

The assembly is covered by a 5-year warranty. Routine inspection of mounting hardware and conduit seals is recommended to maintain code compliance and long-term reliability in hazardous environments.

Build Quality and Physical Characteristics

The bracket measures 5.6 x 5.6 x 4.2 inches, providing a compact footprint for installation in confined or congested areas. The integrated junction box is engineered for hazardous location wiring and includes provisions for secure conduit entry. All hardware is rated for use in classified environments and resists corrosion from chemicals, salt, and moisture.

The assembly is compatible with LED Lighting Supply EXPLA, EXPLB, EXPLC, EXPLD, and EXPLG series explosion proof fixtures. The robust construction supports both surface and pendant mounting methods, maintaining fixture stability under vibration and environmental stress.

Where This Product Fits Best

This explosion proof arm bracket with junction box is intended for hazardous classified environments where directional mounting and sealed wiring are required. It is commonly installed in:

• hazardous location lighting
• explosion proof lighting
• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• offshore rig lighting

The assembly is suitable for environments with flammable gases, vapors, dusts, or fibers. The IP67 rating and UL844, Class I and II Division 1 and 2 certifications support use in both indoor and outdoor hazardous locations, including marine and offshore applications.

Installation and Long-Term Use

Installation requires secure attachment to a rigid surface or pendant conduit in accordance with hazardous location codes. The integrated junction box simplifies wiring and provides a sealed connection point for conduit entry. All mounting and wiring must comply with UL844 and NEC requirements for classified areas.

Routine inspection of mounting hardware, conduit seals, and fixture attachment is recommended to ensure ongoing safety and code compliance. The bracket is designed for long-term use in environments subject to vibration, chemical exposure, and moisture. Replacement or adjustment is rarely required if installed according to manufacturer guidelines.

How This Fixture Is Commonly Used

This bracket is typically installed at mounting heights ranging from 8 to 25 feet, depending on the fixture and application. It is used to provide angled illumination for work areas, walkways, or equipment in hazardous classified spaces. Spacing and layout are determined by the fixture output and required light levels for the specific environment.

Higher output fixtures may allow for wider spacing but can increase glare if mounted too low. The fixed 25-degree angle is selected to optimize coverage for task or area lighting without field adjustment.

Safety, Certifications, and Warranty

This product is UL844 listed for hazardous locations. It is certified for Class I Division 1 Groups A, B, C, D; Class I Division 2 Groups A, B, C, D; Class II Division 1 Groups E, F, G; and Class II Division 2 Groups F, G. The assembly is IP67 rated for dust and water ingress protection.

The bracket and junction box are covered by a 5-year warranty. All components are designed and certified for use in hazardous classified environments, supporting code-compliant installation and long-term safety.
