Product Overview
This 5 Inch Square Pole Tenon Adapter is designed for mounting area and parking lot lighting fixtures to 5 inch square steel or aluminum poles. The adapter provides a 2 3/8 inch round tenon, which is a standard interface for slipfitter and yoke-mount luminaires. The bronze finish matches common pole and fixture colors used in exterior site lighting.
This adapter is typically used when retrofitting or upgrading existing square poles to accept new LED area lights, flood lights, or shoebox fixtures that require a tenon mount. It is suitable for use in parking lots, commercial sites, and roadway perimeter lighting where 5 inch square poles are installed.
Core Performance and Output
The adapter is engineered to provide a secure, stable mounting point for fixtures with a 2 3/8 inch slipfitter or yoke. It is designed to handle the weight and EPA (Effective Projected Area) of standard area and parking lot luminaires commonly installed on 5 inch square poles. The structural integrity of the adapter supports typical fixture loads found in commercial exterior lighting applications.
Performance is dependent on the pole?s structural capacity and the total EPA and weight of the fixtures being mounted. Excessive fixture size or wind load may exceed the pole or adapter?s limits. Always verify compatibility with both the pole and fixture manufacturer?s specifications before installation.
Adjustability and Control Options
This adapter provides a fixed 2 3/8 inch round tenon for mounting. It does not include integrated aiming, tilt, or rotation adjustments; fixture adjustability is determined by the slipfitter or yoke design of the attached luminaire. No electrical or control features are included with the adapter itself.
All aiming, orientation, and control functions must be managed through the fixture or external controls. The adapter?s role is limited to providing a secure mechanical interface between the pole and the luminaire.
Longevity and Reliability
The adapter is constructed for outdoor use with a corrosion-resistant bronze finish. It is designed to withstand typical environmental exposure in parking lots and commercial exterior sites. The one-year warranty covers material and manufacturing defects under normal use conditions.
Long-term reliability is influenced by proper installation, fixture loading, and environmental factors such as wind, moisture, and exposure to de-icing chemicals. Periodic inspection is recommended to ensure continued secure attachment and finish integrity.
Build Quality and Physical Characteristics
The adapter is fabricated to fit 5 inch square poles and provides a 2 3/8 inch round tenon. The bronze finish is standard for commercial exterior lighting hardware. All mounting hardware and fasteners should be compatible with the pole material and finish to prevent galvanic corrosion.
Physical dimensions and weight are optimized for compatibility with standard pole and fixture combinations. The adapter is intended for use with steel or aluminum poles and is not rated for wood, fiberglass, or non-standard pole types.
Where This Product Fits Best
This tenon adapter is suited for commercial and municipal exterior lighting environments where 5 inch square poles are installed and a 2 3/8 inch tenon is required for fixture mounting. It is commonly used in:
- 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 environments exposed to weather, vehicle traffic, and standard commercial site conditions. It is not intended for marine, corrosive, or hazardous locations.
Installation and Long-Term Use
Installation requires access to the top of a 5 inch square pole and secure attachment using appropriate fasteners. The adapter must be properly aligned and tightened to prevent fixture movement or loosening over time. All mounting work should follow local codes and manufacturer guidelines.
Routine inspection is recommended, especially in high-wind or high-traffic areas. Check for signs of corrosion, fastener loosening, or finish degradation. Re-tighten or replace hardware as needed to maintain safe operation.
How This Fixture Is Commonly Used
The adapter is typically installed at the top of 5 inch square steel or aluminum poles to support one or more area or parking lot fixtures with slipfitter mounts. Mounting heights generally range from 15 to 30 feet, depending on site requirements and pole length.
Spacing and layout are determined by the lighting design and fixture output. Using higher output fixtures may reduce the number of poles required but can increase wind load and structural demands on the adapter and pole.
Safety, Certifications, and Warranty
This adapter is intended for use in commercial exterior lighting installations. It is finished in bronze for corrosion resistance and includes a one-year warranty. No additional safety certifications are specified for this accessory.
All installations must comply with local codes and standards for exterior lighting hardware. Use only with compatible poles and fixtures to ensure safe operation.
