Explosion Proof Wall Mount Arm Bracket | Class 1 Div 2 | Class 2 Div 2

Product Overview

This Explosion Proof Wall Mount Arm Bracket is built for hazardous location installations where fixtures must be mounted to vertical surfaces. The bracket is designed specifically for use with our Explosion Proof EXPLA and EXPLB fixture lines.

The bracket carries UL844 certification for hazardous locations, rated for Class 1 Division 2 (Groups E, F, G) and Class 2 Division 1 (Groups A, B, C, D) environments. Dimensions measure 5.6 x 5.6 x 4.2 inches.

Where This Product Fits Best

This bracket is intended for wall-mounted applications in classified hazardous areas where combustible dust or ignitable fibers may be present. Class 1 Division 2 covers locations where flammable gases or vapors are not normally present in ignitable concentrations but may exist under abnormal conditions. Class 2 Division 1 covers locations where combustible dust is present in the air under normal operating conditions.

Typical environments include grain processing facilities, chemical handling areas, petroleum refineries, paint spray booths, and other spaces requiring hazardous location rated equipment. The bracket allows EXPLA and EXPLB fixtures to extend from a wall surface rather than mounting directly overhead.

Performance and Functional Considerations

The bracket is rated for the same hazardous location classifications as the EXPLA and EXPLB fixtures it supports. This maintains compliance throughout the mounting assembly in classified areas.

Group ratings cover specific hazardous materials. Groups A, B, C, and D address gases and vapors including acetylene, hydrogen, ethylene, and propane. Groups E, F, and G cover metal dusts, carbonaceous dusts, and grain or fiber dusts.

Installation and Long-Term Use

The compact 5.6 x 5.6 x 4.2 inch footprint allows mounting in spaces where larger brackets would interfere with equipment or traffic. Wall mounting positions the fixture away from the mounting surface, providing clearance for the fixture body and directing light output as needed for the application.

All hardware and connections in hazardous locations must maintain the integrity of the classified installation. The bracket should be installed according to NEC requirements for the applicable hazardous location class and division.

How This Fixture Is Commonly Used

Facilities use this bracket when overhead mounting is not practical or when light needs to be directed from a wall-mounted position. In processing areas with low ceilings or obstructed overhead space, wall mounting can position fixtures where they provide useful illumination without interfering with operations.

The arm extension moves the fixture away from the wall surface. This is useful in applications where equipment, ductwork, or structural elements would block a flush-mounted fixture. Once installed, the bracket requires no adjustment or interaction during normal facility operation.

Safety, Certifications, and Warranty

This bracket is UL844 listed for hazardous locations. It is rated Class 1 Division 2 for Groups E, F, and G, and Class 2 Division 1 for Groups A, B, C, and D.

Use with EXPLA and EXPLB fixtures maintains a listed assembly for the covered hazardous location classifications.
