Explosion Proof Hook Adapter | 3/4 Inch NTP | Class 1 Div 2 | Class 2 Div 2

Product Overview

This explosion proof hook adapter is designed for use with our Explosion Proof EXPLA and EXPLB fixtures. It provides a secure mounting interface for hazardous location lighting installations where a hook-style suspension is required.

The adapter features a 3/4 inch NTP thread and is built to meet hazardous location requirements. It is suitable for environments where explosive gases, vapors, or dusts may be present under abnormal conditions.

Dimensions for the adapter are 5.6 x 5.6 x 4.2 inches. The construction supports compatibility with the specified fixture families and hazardous area classifications.

Where This Product Fits Best

This hook adapter is intended for hazardous locations classified as Class 1 Division 2 Groups A, B, C, D and Class 2 Division 1 Groups E, F, G. It is suitable for use in facilities where flammable gases, vapors, or combustible dusts may be present intermittently.

Common installation sites include chemical processing plants, refineries, grain handling facilities, and other industrial spaces requiring explosion proof lighting solutions. The adapter is used where a hook mount is preferred or required for fixture suspension.

It is not intended for use outside of the specified hazardous location classifications. Compatibility is limited to the listed EXPLA and EXPLB fixture series.

Performance and Functional Considerations

The adapter is built to meet UL844 hazardous location requirements. It supports safe fixture mounting in environments with potential exposure to explosive gases or dusts as defined by the listed classes and groups.

The 3/4 inch NTP threading provides a standard connection point for compatible conduit or mounting hardware. The adapter?s dimensions allow for integration with the specified fixture models without modification.

There are no integrated electrical or control features. The adapter serves as a mechanical mounting solution only.

Installation and Long-Term Use

Installation requires standard tools for hazardous location fixture mounting. The 3/4 inch NTP thread is compatible with typical rigid conduit and hook suspension hardware used in classified environments.

Once installed, the adapter provides a stable and secure mounting point for the fixture. The construction supports long-term use in industrial environments where vibration, dust, and exposure to chemicals may be present.

Routine inspection of mounting hardware is recommended as part of standard facility maintenance in hazardous locations. The adapter does not require ongoing adjustment or servicing beyond standard checks for mechanical integrity.

How This Fixture Is Commonly Used

After installation, the hook adapter allows you to suspend compatible explosion proof fixtures from overhead structures using a hook mount. This method is often chosen for ease of fixture removal and reinstallation during maintenance or reconfiguration.

In day-to-day operation, the adapter does not require user interaction. It remains fixed in place, supporting the fixture and maintaining the hazardous location rating of the overall installation.

If you need to relocate or service the fixture, the hook mount design allows for straightforward removal and reattachment without disturbing conduit connections above the adapter.
