Explosion Proof Slipfitter Adapter | 2 3/8 Inch Tenon

Product Overview

Explosion Proof Slipfitter Adapter with 2 3/8 Inch Tenon is designed to mount explosion proof light fixtures to round poles in hazardous locations. This adapter is compatible with Class I Division 2 and Class II Division 2 rated fixtures, supporting secure installation in environments where flammable gases, vapors, or dusts may be present. Typical use includes oil and gas facilities, chemical processing plants, and other industrial sites requiring hazardous location lighting on pole structures.

The slipfitter adapter provides a robust mounting interface for explosion proof fixtures, allowing for precise aiming and secure attachment to standard 2 3/8 inch round tenons. It is engineered for use with LED Lighting Supply?s EXPLA, EXPLB, EXPLSTA1, and EXPLSTA2 explosion proof fixture families.

Core Performance and Output

This slipfitter adapter is built to support the mechanical and environmental demands of hazardous location lighting. It is rated for use with Class I Division 2 and Class II Division 2 fixtures, ensuring compatibility with explosion proof luminaires in both gas/vapor and dust environments. The 2 3/8 inch tenon interface provides a stable mounting point for fixtures up to the maximum weight and EPA specified by the fixture manufacturer.

The adapter?s structural integrity is suitable for outdoor and industrial settings, maintaining fixture alignment under wind load and vibration. Excessive fixture weight or mounting on undersized poles may compromise stability; always verify pole and fixture compatibility before installation.

Adjustability and Control Options

The slipfitter design allows for horizontal and vertical adjustment of the attached fixture, supporting precise aiming for task or area illumination. The tenon interface is compatible with standard pole-top mounting hardware, enabling straightforward integration with existing round poles.

No electrical or lighting control features are integrated into the adapter. All fixture-level controls and wiring must be managed through the attached explosion proof luminaire.

Longevity and Reliability

The adapter is constructed from corrosion-resistant materials suitable for harsh industrial and outdoor environments. All hardware and finishes are selected to withstand exposure to chemicals, moisture, and UV, supporting long-term reliability in hazardous locations.

Mechanical fasteners and locking mechanisms are designed for repeated adjustment and maintenance cycles without loss of holding strength. Periodic inspection is recommended to ensure continued secure attachment, especially in high-vibration or corrosive environments.

Build Quality and Physical Characteristics

The slipfitter adapter features a heavy-duty body with a 2 3/8 inch round tenon, compatible with standard pole-top dimensions. All components are sealed and finished to prevent ingress of dust and moisture, supporting use in both indoor and outdoor hazardous locations.

Mounting hardware is included for secure attachment to round poles. The adapter?s form factor is compact, minimizing wind profile while providing robust support for explosion proof fixtures.

Where This Product Fits Best

This slipfitter adapter is intended for hazardous location lighting applications where explosion proof fixtures must be mounted to round poles. It is commonly used in environments with flammable gases, vapors, or combustible dusts, and where pole-mounted lighting is required for area or task illumination.

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

The adapter is suitable for both indoor and outdoor use, including corrosive and marine environments. It is not intended for use with non-explosion proof fixtures or in non-hazardous locations.

Installation and Long-Term Use

Installation requires securing the adapter to a round pole with the included hardware, then attaching the compatible explosion proof fixture to the tenon. All mounting work should follow hazardous location safety protocols and local code requirements. The adapter supports both new installations and retrofit upgrades where pole-mounted hazardous location lighting is needed.

Routine inspection of mechanical fasteners is recommended, especially in environments with vibration or corrosive exposure. The adapter?s design allows for fixture aiming adjustments without removal from the pole. Long-term performance depends on proper installation and periodic maintenance.

How This Fixture Is Commonly Used

The slipfitter adapter is typically installed at mounting heights ranging from 12 to 30 feet, depending on the lighting requirements and pole height. Spacing between pole-mounted fixtures is determined by the area coverage and light distribution of the attached explosion proof luminaire.

In oil and gas facilities, chemical plants, and refineries, these adapters are used to position fixtures for perimeter, roadway, or process area illumination. Higher mounting heights reduce fixture count but may require higher output fixtures for uniform coverage.

Safety, Certifications, and Warranty

This adapter is rated for use with Class I Division 2 and Class II Division 2 explosion proof fixtures. All materials and finishes are selected for hazardous location suitability. The product is covered by LED Lighting Supply?s standard warranty for hazardous location accessories.

Always confirm compatibility with the specific fixture model and hazardous location classification before installation. Follow all site safety and code requirements during mounting and maintenance.
