4 Inch Round Pole Tenon Adapter | 2 3/8 Inch Tenon | Bronze

Product Overview

The 4 Inch Round Pole Tenon Adapter with a 2 3/8 inch tenon is designed for mounting area and parking lot lighting fixtures to round steel or aluminum poles. This adapter provides a secure interface between the pole and standard slipfitter or tenon-mount luminaires. The bronze finish matches common site lighting hardware and resists corrosion in typical outdoor environments. This adapter is typically used in exterior lighting upgrades or new installations where round poles require a tenon for fixture mounting.

Commonly installed in parking lots, commercial sites, and roadway perimeters, this adapter supports standard area lighting fixtures that require a 2 3/8 inch tenon. The design is compatible with most 4 inch outside diameter round poles found in commercial and municipal exterior lighting projects.

Core Performance and Output

This tenon adapter is engineered to provide a stable mounting point for fixtures with a 2 3/8 inch slipfitter. The structural design supports the weight and EPA of typical area and parking lot luminaires within standard pole loading guidelines. The adapter maintains fixture alignment and resists rotation under wind load when properly installed.

Performance is dependent on the pole?s structural capacity and the total fixture load. Excessive fixture weight or EPA beyond pole or adapter ratings can compromise stability. Always verify compatibility with both the pole and fixture specifications before installation.

Adjustability and Control Options

This adapter provides a fixed 2 3/8 inch round tenon for slipfitter-mounted fixtures. It does not include integrated aiming, tilt, or rotation adjustments. Fixture adjustability is determined by the slipfitter or mounting hardware used with the adapter.

No electrical or control features are included. All wiring and controls are managed through the fixture and pole assembly.

Longevity and Reliability

The adapter is constructed from materials suitable for outdoor use and finished in bronze for corrosion resistance. When installed on compatible poles and used within rated load limits, the adapter provides reliable long-term performance in exterior environments.

Routine inspection of mounting hardware and pole condition is recommended as part of standard site lighting maintenance. The product includes a 1 year warranty covering material and manufacturing defects.

Build Quality and Physical Characteristics

This adapter is designed for 4 inch outside diameter round poles and provides a 2 3/8 inch round tenon. The bronze finish is durable and matches most commercial site lighting hardware. The adapter is compatible with standard slipfitter fixtures used in area and parking lot lighting.

All mounting hardware should be selected to match the pole material and site requirements. The adapter is not intended for use with square poles or non-standard pole diameters.

Where This Product Fits Best

This tenon adapter is suited for exterior environments where round poles are used to support area and parking lot lighting. It is commonly deployed in commercial, municipal, and campus settings requiring secure mounting of slipfitter fixtures.

• parking lot lighting
• area lighting
• commercial site lighting
• roadway lighting
• sports facility lighting
• campus lighting
• industrial yard lighting
• dealership lighting

The adapter is suitable for outdoor use in standard weather conditions. Not intended for use in marine, corrosive, or high-wind specialty environments without additional engineering review.

Installation and Long-Term Use

The adapter is installed by securing it to the top of a 4 inch round pole using appropriate hardware. The tenon provides a standard interface for slipfitter-mounted fixtures. Installation should follow all site safety protocols and pole manufacturer guidelines.

Long-term reliability depends on proper torque of mounting hardware and periodic inspection for corrosion or loosening. The adapter does not require routine maintenance beyond standard site lighting checks.

How This Fixture Is Commonly Used

This adapter is typically used to mount area or parking lot fixtures at heights ranging from 15 to 30 feet, depending on pole length and site requirements. Fixture spacing and layout are determined by the lighting design and desired coverage.

Multiple adapters may be installed on a single pole for multi-fixture mounting, provided pole loading limits are observed. Using higher output fixtures may reduce the number of poles required but can increase wind load and structural demands.

Safety, Certifications, and Warranty

The adapter is designed for exterior use and finished for corrosion resistance. It is not rated for hazardous or marine environments. All installations must comply with local codes and pole manufacturer recommendations.

Includes a 1 year warranty. No additional certifications are specified for this accessory.
