Tenon adapters connect existing light poles to modern LED fixtures, providing secure mounting solutions that upgrade your lighting infrastructure. These commercial-grade brackets fit various pole configurations and offer the structural integrity needed for demanding outdoor use. For best results, match your adapter size to your pole's outside diameter to ensure proper fit and load distribution.
What Are Light Pole Tenon Adapters?
Light pole tenon adapters serve as mechanical interfaces, expanding single-pole mounting into multi-fixture platforms. Instead of adding new poles, these brackets create mounting points for LED fixtures, cameras, or signage on existing poles. Top-mount adapters handle main lighting loads, while side-mount versions support auxiliary equipment without compromising structure.

- 4 inch round pole adapter
- 4 inch square pole adapter
- 5 inch round pole adapter
- 5 inch square pole adapter
Common Applications
Tenon adapters are used in municipal lighting upgrades where budgets do not allow full infrastructure replacement:
- Highway and arterial road lighting modernization
- Retail parking lot upgrades with LED area lights
- Athletic facility lighting needing precise beam control
- Security systems combining lighting and cameras
- Wayfinding signage in urban areas
- HID-to-LED conversions using existing poles
Types of Tenon Adapters
Round pole adapters are common in street lighting, offering 360-degree rotation for precise fixture placement. Square pole adapters suit architectural lighting where clean lines are important. Reducer adapters resolve mismatches between fixture tenons and pole sizes, avoiding custom fabrication. Slipfitter adapters allow angular adjustment during installation, which is important for proper light distribution. Material choice affects longevity - 6061-T6 aluminum resists corrosion and has a high strength-to-weight ratio, while marine-grade finishes extend service life in salt-air environments. Bulk pricing is available for larger projects. Always verify compatibility - fixture weight, EPA ratings, and mounting hardware must match adapter specs. LED area lights, floodlights, and architectural fixtures each require specific mounting considerations.
Selecting the Proper Tenon Adapter
Adapter selection depends on engineering specifications beyond just size:
- Fixture count and spacing for optimal light coverage
- Combined weight and EPA calculations for safety
- Pole material, age, and condition for load capacity
- Photometric needs affecting arm length and angle
- Special coatings for coastal or industrial environments
- Local wind and seismic requirements per code
- Custom fabrication for unique architectural needs
Installation Considerations
Structural analysis is important when adding fixtures to existing poles. Poles with wall thickness below 0.125 inches may need reinforcement for heavier LED assemblies. Wind load calculations should include fixture EPA, mounting height, and local weather to ensure stability and safety.
These heavy-duty brackets allow complex lighting setups without replacing poles. Steel construction with powder-coated finishes offers long-term durability in harsh weather. Aluminum options are preferred for coastal areas due to corrosion resistance, while steel versions are suited for higher wind loads inland. When retrofitting, verify load calculations to avoid overloading poles and maximize your investment. Most quality adapters are priced under $100, offering significant savings over new pole installations. Accurate measurements of pole diameter, wall thickness, and fixture specs are essential for selecting the right adapter. Our Product Specialists can assist with technical support for installations requiring wind load calculations or structural analysis.
Key Features and Benefits
Commercial-grade construction ensures reliability for municipal and industrial lighting. High-strength materials can withstand 150+ mph wind loads when properly specified and installed. Weather-resistant finishes protect appearance and performance over time:
- Single to quad-arm configurations maximize pole use
- Compatible with round, square, and tapered poles
- TGIC polyester powder coating offers strong UV resistance
- Engineered mounting angles improve photometric performance
- Standard hardware simplifies installation and reduces labor
Tenon Adapters for Light Poles Frequently Asked Questions
What are tenon adapters used for in LED lighting?
Tenon adapters function as mechanical interfaces that expand single-pole mounting capacity into multi-fixture platforms, creating mounting points for LED fixtures, cameras, or signage on existing infrastructure without installing additional poles.
What sizes of tenon adapters are available?
Available configurations include 3 inch round, 4 inch round, 4 inch square, 5 inch round, and 5 inch square pole adapters - match your adapter size to your pole''s outside diameter for optimal fit and load distribution.
What materials are tenon adapters made from?
6061-T6 aluminum resists corrosion while maintaining superior strength-to-weight ratios, and steel construction with powder-coated finishes ensures long-term performance in harsh weather conditions. Aluminum options suit coastal installations due to superior corrosion resistance, while steel versions handle higher wind loads in inland applications.
What finishes are available for tenon adapters?
TGIC polyester powder coating provides superior UV resistance, and marine-grade finishes extend service life in salt-air environments where standard coatings fail prematurely.
How many fixtures can a tenon adapter support?
Configurations range from single through quad-arm configurations to maximize pole utilization.
What wind loads can tenon adapters withstand?
High-strength materials withstand 150+ mph wind loads when properly specified and installed.
What types of poles are compatible with tenon adapters?
Round, square, and tapered pole compatibility covers existing infrastructure, with round pole adapters offering 360-degree rotation for precise fixture positioning and square pole versions integrating with architectural lighting.
What is a reducer adapter?
Reducer adapters solve compatibility issues when fixture tenons don''t match pole dimensions, eliminating the need for custom fabrication.
What are common applications for tenon adapters?
Applications include highway and arterial road lighting modernization, retail parking lot illumination with LED area lights, athletic facility installations, integrated security systems combining lighting with surveillance cameras, and HID-to-LED conversion projects.
What factors should be considered when selecting a tenon adapter?
Selection factors include fixture count and spacing, combined weight and EPA calculations for structural safety, pole material and condition assessment, photometric requirements influencing arm length, and local wind load and seismic requirements per building codes.
What installation considerations are important for tenon adapters?
Wall thickness below 0.125 inches may require reinforcement for heavier LED assemblies, and wind load calculations must factor in fixture EPA, mounting height, and local weather patterns. Product Specialists provide technical support for complex installations where wind load calculations and structural analysis become critical factors.
How much do tenon adapters cost?
Competitive pricing keeps most quality adapters under $100, delivering exceptional value compared to new pole installation costs, with larger installations benefiting from volume discounts.
