Our 20 Foot Class 3 CCA Treated Southern Yellow Pine Poles are grown, debarked, and treated in the United States. They are manufactured to ANSI O5.1 specification. Poles are pressure treated and preservative treated to the latest American Wood Preservers Association standards to prevent damage from termites, decay and rot regardless of the species used.
Delivery is made with a flatbed truck and the customer is responsible for offloading. Offloading requires a forklift 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 3 Wood Pole is manufactured from Southern Yellow Pine and pressure treated with CCA preservative. It is designed for use as a structural support in outdoor lighting and utility distribution systems. The pole meets ANSI O5.1 Class 3 standards and is suitable for direct burial installation, with 16 feet above grade and 4 feet below grade. Typical installations include sports field lighting, rural roadway lighting, and utility distribution on agricultural or municipal properties.
With a weight range of 500 to 600 lbs and a minimum top circumference of 23 inches, this pole provides a balance of strength and manageable handling for field crews. The CCA treatment protects against decay, termites, and rot, supporting long-term performance in exposed environments.
Core Performance and Output
This Class 3 wood pole is engineered for moderate structural loads and is commonly used to support lighting fixtures, utility lines, or area lighting systems. The 20-foot total length, with 16 feet above grade, is appropriate for mounting luminaires or utility hardware at heights suitable for small to mid-sized sports fields, parking lots, and rural roadways.
The pole?s diameter and circumference meet ANSI O5.1 requirements, providing reliable support for typical fixture and bracket loads within the class rating. Excessive wind loading or mounting of oversized fixtures may exceed the structural limits of this class and height. For installations in high-wind or coastal areas, verify EPA and load calculations based on site conditions and fixture selection.
Adjustability and Control Options
This wood pole does not include integrated adjustability or control features. Fixture mounting, bracket orientation, and hardware selection determine the final aiming and adjustment capabilities. The pole can accommodate a range of mounting arms, crossarms, and utility hardware as required by the application.
Control systems, such as photocells or wireless controls, are installed as part of the lighting or utility equipment mounted to the pole, not the pole itself. Ensure compatibility of mounting hardware and controls with the pole?s diameter and material.
Longevity and Reliability
The Southern Yellow Pine construction, combined with CCA pressure treatment, provides resistance to decay, rot, and insect damage. This supports reliable long-term use in outdoor environments, including areas with high moisture or soil contact.
Routine inspection for physical damage, surface checking, or hardware loosening is recommended as part of ongoing maintenance. The 1-year warranty covers material and manufacturing defects. Actual service life is influenced by site conditions, installation quality, and maintenance practices.
Build Quality and Physical Characteristics
This pole is manufactured in the United States from Southern Yellow Pine, debarked and pressure treated to meet current American Wood Preservers Association standards. The minimum top outside diameter is 7.3 inches, with 8.6 inches at 6 feet from the butt, supporting a range of bracket and arm installations.
The pole is supplied for direct burial, with a 4-foot embedment depth standard for this height and class. The CCA treatment is applied to the full length of the pole, ensuring consistent protection throughout the buried and exposed sections.
Where This Product Fits Best
This 20 Foot Class 3 wood pole is suited for outdoor environments where moderate mounting heights and structural loads are required. It is commonly used in sports field lighting, rural roadway lighting, and utility distribution on agricultural or municipal properties. The pole?s treated wood construction is appropriate for locations where corrosion resistance and non-conductivity are priorities.
- baseball field lighting
- football field lighting
- utility distribution
- area lighting
- parking lot lighting
- rural roadway lighting
- agricultural property lighting
- municipal lighting
The CCA-treated Southern Yellow Pine construction provides durability in wet, humid, or insect-prone environments. Direct burial installation is standard for this pole type and height.
Installation and Long-Term Use
Direct burial installation requires excavation to a minimum depth of 4 feet, with backfill and compaction to stabilize the pole. Standard pole handling equipment is required due to the 500?600 lb weight. Hardware selection should match the pole?s diameter and wood material for secure attachment of fixtures or utility equipment.
Long-term use depends on proper installation, periodic inspection, and maintenance of both the pole and mounted equipment. CCA treatment supports extended service life, but poles should be monitored for surface checking, decay at ground line, and hardware integrity over time.
How This Fixture Is Commonly Used
Typical mounting heights are 16 feet above grade, supporting area lighting fixtures, sports field luminaires, or utility crossarms. Fixture spacing and layout depend on the lighting design, field size, and required light levels. Poles are often spaced to provide uniform coverage for sports fields, parking lots, or rural roadways.
Higher mounting heights can reduce fixture count but may require larger fixtures or increased pole class for wind load. For clustered or multi-fixture installations, verify total load and EPA against the pole?s class rating.
Safety, Certifications, and Warranty
This pole is manufactured to ANSI O5.1 Class 3 standards. CCA treatment meets American Wood Preservers Association requirements. The product is covered by a 1-year warranty against material and manufacturing defects.
Follow all applicable safety guidelines for pole handling, installation, and working at height. Use appropriate PPE and lifting equipment during installation and maintenance.
