Explosion Proof Arm Bracket With Junction Box | 90 Degree Mount | Class 1 Div 1

Product Overview

This explosion proof 90-degree wall arm bracket with junction box is designed for mounting LED Lighting Supply explosion proof fixtures in hazardous locations. The bracket provides a secure, right-angle wall mount solution for environments where Class I Division 1 and Division 2, as well as Class II Division 1 and Division 2 ratings are required. Typical installations include chemical processing facilities, paint booths, and areas with flammable gases or dusts.

The bracket is compatible with our EXPLA, EXPLB, EXPLC, EXPLD, and EXPLG explosion proof fixture families. It is engineered for use with 100W to 200W fixtures, supporting output levels from 14,000 to 28,000 lumens. The included junction box simplifies wiring in hazardous environments and maintains the integrity of the explosion proof system.

Core Performance and Output

This arm bracket is built to support the structural and environmental demands of hazardous location lighting. It maintains the fixture?s Class I Div 1, Class I Div 2, Class II Div 1, and Class II Div 2 compliance when installed per code. The bracket and junction box are IP67 rated, providing full protection against dust ingress and temporary immersion in water.

The bracket is designed for wall mounting at 90 degrees, supporting fixtures in the 100W?200W range. The assembly is suitable for mounting heights typical of hazardous location lighting, generally between 10 and 25 feet. Excessive fixture weight or improper mounting can compromise the explosion proof rating and should be avoided.

Adjustability and Control Options

This bracket provides a fixed 90-degree mounting angle for wall installations. There are no adjustable tilt or swivel features. The included junction box allows for secure, code-compliant wiring connections in hazardous environments.

Control options such as dimming or occupancy sensors are determined by the fixture, not the bracket. The bracket does not interfere with fixture-integrated controls or wiring methods approved for hazardous locations.

Longevity and Reliability

The bracket and junction box are constructed from corrosion-resistant materials suitable for harsh industrial and chemical environments. The IP67 rating ensures long-term protection against dust and water ingress, supporting reliable operation in both indoor and outdoor hazardous areas.

All components are designed for extended service life and minimal maintenance. The 5-year warranty covers material and manufacturing defects under normal operating conditions.

Build Quality and Physical Characteristics

The bracket measures 5.6 x 5.6 x 4.2 inches and is engineered for compatibility with LED Lighting Supply explosion proof fixtures. The assembly is robust, with all hardware and enclosure components meeting hazardous location requirements.

The junction box is integrated into the bracket design, providing a compact and secure solution for fixture mounting and wiring. All surfaces are sealed to prevent ingress of dust, moisture, and contaminants.

Where This Product Fits Best

This explosion proof wall arm bracket with junction box is intended for hazardous locations where wall-mounted lighting is required. It is suitable for environments with flammable gases, vapors, dusts, or fibers, and where compliance with Class I and Class II Division 1 and 2 standards is mandatory.

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

The bracket is suitable for both indoor and outdoor use, including areas exposed to water spray, dust, or corrosive atmospheres. It is not intended for non-hazardous or general-purpose lighting applications.

Installation and Long-Term Use

Installation requires secure attachment to a structurally sound wall surface using appropriate fasteners for the environment. The bracket is designed for use with compatible LED Lighting Supply explosion proof fixtures and must be installed according to hazardous location electrical codes.

The integrated junction box simplifies wiring and maintains the explosion proof integrity of the system. Routine inspection of mounting hardware and enclosure seals is recommended to ensure continued compliance and performance.

How This Fixture Is Commonly Used

This bracket is typically installed at mounting heights between 10 and 25 feet, depending on the fixture wattage and required light levels. It is used to position explosion proof fixtures for wall-mounted area or task lighting in hazardous environments.

Spacing and layout are determined by the fixture?s output and the specific lighting requirements of the space. Higher output fixtures may allow for wider spacing but can increase glare if mounted too low.

Safety, Certifications, and Warranty

This product is UL844 listed for hazardous locations. It is certified for Class I Div 1 Groups A, B, C, D; Class I Div 2 Groups A, B, C, D; Class II Div 1 Groups E, F, G; and Class II Div 2 Groups F, G. The assembly is IP67 rated and includes a 5-year warranty.

All components are designed to maintain hazardous location compliance when installed with compatible fixtures and according to code. The bracket and junction box are suitable for use in environments requiring explosion proof and dust-tight equipment.
