Delivery is made with a flatbed truck and the customer is responsible for offloading. Offloading requires a fork lift or appropriate similar vehicle to offload - customer supplied. Customers are responsible for any costs associated with delivery rescheduling because of improper scheduling or not having the proper offloading equipment or area to store poles available at the time of delivery. Please contact a sales representative prior to purchasing to ensure all the project details are clear.
Pricing: Does not include cost of shipping. Shipping is available to the lower 48 USA states. We can supply a budgetary shipping quote or a firm shipping quote that is good for 14 days.
Disclaimer: LED Lighting Supply is not responsible for improper loading (ie what is mounted to the pole), installation costs, or foundation design of light poles. Dimensions and specifications of poles are subject to change without notice but the pole top and butt dimensions will always be within ANSI specifications. Wood poles are the ideal option for most field projects as concrete poles require more frequent maintenance and replacement. While our main product line is southern yellow pine, we at times are able to offer other species including Douglas fir and red pine. CCA treatment generally will result in the poles being free of insects for decades to come.
Please be advised that our wood poles are covered solely by a 1-year workmanship warranty, which ensures that the poles are free from defects from the manufacturing process, and structural integrity, for a period of one year from the date of purchase. This warranty does not cover damage resulting from external factors, misuse, or normal wear and tear.

Product Overview
This 20 Foot Class 6 Wood Pole is manufactured from Southern Yellow Pine and pressure treated with CCA preservative. It is designed for direct burial installation in outdoor environments where wood poles are required for mounting area lighting, field lighting, or utility distribution equipment. The pole meets ANSI O5.1 standards and is suitable for use in sports field lighting, rural roadway lighting, and agricultural property lighting.
With a total length of 20 feet and a Class 6 structural rating, this pole provides a balance of manageable weight and reliable support for light fixtures, cameras, or utility hardware. Typical above-grade height is 16 feet after burial, making it appropriate for small to mid-scale lighting and utility projects in municipal, recreational, and agricultural settings.
Core Performance and Output
This pole supports a range of light fixtures and utility loads within the Class 6 structural limits. The minimum top circumference is 17 inches, and the pole diameter at 6 feet from the butt is 6.7 inches, providing adequate strength for mounting single or dual fixtures with moderate EPA and weight. The 20-foot length allows for 16 feet of exposed height after 4 feet of direct burial, which is standard for this class and application range.
Wind load and EPA capacity are determined by the Class 6 rating and wood species. This pole is suitable for mounting fixtures and equipment with a combined EPA and weight that does not exceed the structural limits of a Class 6 Southern Yellow Pine pole. Excessive fixture weight or large sail area attachments may require a higher class or larger diameter pole.
Adjustability and Control Options
Wood poles do not offer integrated adjustability or built-in control features. Fixture mounting locations can be field-drilled or pre-drilled as needed for brackets, arms, or hardware. Height above grade is fixed at 16 feet after installation. Control systems, such as photocells or wireless nodes, must be specified and installed separately on the pole or attached fixtures.
Field modifications are possible but should be limited to maintain structural integrity. All control wiring and conduit runs must be planned for direct burial or surface mounting as required by local codes and project needs.
Longevity and Reliability
The pole is pressure treated with CCA to resist decay, rot, and termite damage. Southern Yellow Pine is a standard species for utility poles, offering reliable performance in outdoor environments. Service life depends on soil conditions, installation quality, and exposure, but CCA treatment extends durability in most climates.
Routine inspection is recommended to monitor for mechanical damage, woodpecker activity, or ground line decay over time. The pole carries a 1-year warranty from the manufacturer.
Build Quality and Physical Characteristics
This pole is manufactured in the United States from Southern Yellow Pine, debarked, and treated to meet ANSI O5.1 and American Wood Preservers Association standards. The pole weighs between 300 and 400 lbs, with a minimum top outside diameter of 5.4 inches. Circumference and diameter are specified for both the top and 6 feet from the butt to ensure compliance with Class 6 requirements.
Direct burial installation requires a 4-foot embedment below grade. The CCA treatment provides protection against biological degradation, and the wood construction offers non-conductive properties compared to steel or aluminum poles.
Where This Product Fits Best
This 20 Foot Class 6 Wood Pole is suited for outdoor environments where moderate mounting heights and wood construction are preferred or required. It is commonly used for sports field lighting, rural area lighting, and utility distribution in non-urban settings.
- baseball field lighting
- sports field lighting
- area lighting
- rural roadway lighting
- agricultural property lighting
- parking lot lighting
- municipal lighting
- utility distribution
The pole is suitable for direct burial in soil and is compatible with standard wood pole mounting hardware. It is not recommended for environments with extreme corrosive exposure or where higher mounting heights or heavier loads are required.
Installation and Long-Term Use
Direct burial installation requires excavation to a depth of 4 feet, with proper backfill and compaction to ensure stability. The pole weight of 300?400 lbs typically requires mechanical handling or equipment for safe placement. Standard wood pole hardware and brackets can be used for fixture and equipment mounting.
Long-term use depends on soil drainage, ground contact conditions, and periodic inspection. CCA treatment provides protection, but ground line decay should be monitored over time. Replacement or reinforcement may be needed if significant deterioration is observed at the base or attachment points.
How This Fixture Is Commonly Used
Poles of this size and class are typically installed with 16 feet exposed above grade, supporting one or two area lights, field lights, or utility devices. Fixture mounting heights are usually set between 14 and 16 feet, depending on the application and desired coverage. Spacing between poles varies based on light distribution requirements and field layout, with wider spacing possible for area lighting and closer spacing for sports field uniformity.
Using higher output fixtures can reduce the number of poles required but may increase glare or require careful aiming to avoid spill light. Fixture EPA and weight must always be checked against the Class 6 pole limits before installation.
Safety, Certifications, and Warranty
This pole is manufactured to ANSI O5.1 standards and treated to American Wood Preservers Association requirements. CCA treatment provides resistance to decay and insect damage. The pole is non-conductive and suitable for use in areas where electrical isolation is required.
A 1-year manufacturer warranty is provided. All installation and handling should follow OSHA and local safety guidelines for wood pole work.
Frequently Asked Questions
Q: What is the maximum fixture weight and EPA this pole can support?
A: The maximum supported weight and EPA depend on the Class 6 rating and Southern Yellow Pine properties. Typical Class 6 wood poles at this height are suitable for moderate area lights or utility loads. Always verify fixture and bracket specifications against pole class tables before installation.
Q: Can this pole be used for both lighting and security camera mounting?
A: Yes, this pole can support both area lighting fixtures and security cameras, provided the combined weight and EPA do not exceed Class 6 limits.
Q: What is the required burial depth for installation?
A: The pole requires 4 feet of direct burial below grade, resulting in 16 feet of exposed height above ground.
