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 1 Treated Southern Yellow Pine Wood Pole is designed for use in light pole and utility pole installations requiring direct burial. The pole is manufactured from Southern Yellow Pine, pressure treated with CCA preservative, and meets ANSI O5.1 standards. Typical installations include sports field lighting, rural roadway lighting, and utility distribution where wood poles are preferred for their structural and environmental characteristics.
With a total length of 20 feet and a direct burial depth of 4 feet, this pole provides 16 feet of height above grade. It is suitable for mounting area lighting, sports field fixtures, or supporting utility lines in outdoor environments where wood is specified or required.
Core Performance and Output
This Class 1 wood pole supports demanding structural loads and is rated for installations where higher strength and durability are required. The minimum pole top circumference is 27 inches, with a minimum circumference of 31 inches measured 6 feet from the butt. The pole top outside diameter is 8.6 inches, and the diameter 6 feet from the butt is 9.8 inches.
Typical pole weight ranges from 600 to 800 lbs. The CCA treatment provides long-term resistance to decay, rot, and insect damage. Structural performance is suitable for mounting sports field lighting, area lighting, or utility distribution hardware within the limits of Class 1 wood pole design. Excessive fixture weight or wind load may require additional engineering review for mounting height and EPA limits.
Adjustability and Control Options
This wood pole is not adjustable in height or form factor after installation. Fixture mounting locations can be field-drilled or pre-drilled as required for brackets, arms, or crossarms. The pole supports standard hardware for lighting, utility, or area applications.
No integrated control options are included. Controls, sensors, or photocells must be specified and installed with the mounted fixtures or hardware as required by the application.
Longevity and Reliability
The pole is pressure treated with CCA preservative to meet American Wood Preservers Association standards. This treatment provides resistance to termites, decay, and rot for long-term outdoor use. Southern Yellow Pine is selected for its structural strength and durability in utility and lighting applications.
Expected service life depends on site conditions, installation quality, and maintenance. Direct burial installation requires proper backfill and drainage to maximize longevity. Routine inspection is recommended to monitor for mechanical damage or environmental degradation over time.
Build Quality and Physical Characteristics
Each pole is grown, debarked, and treated in the United States. The wood is Southern Yellow Pine, selected for high strength-to-weight ratio and suitability for structural pole use. The pole is manufactured to ANSI O5.1 specification for Class 1 wood poles.
CCA treatment is applied by pressure process to ensure deep preservative penetration. The pole is supplied in a natural wood finish, with dimensions and weight consistent with Class 1 requirements. Direct burial installation is supported by the specified butt diameter and length below grade.
Where This Product Fits Best
This 20 foot Class 1 treated wood pole is suited for outdoor environments where wood poles are required or preferred for lighting, utility, or area support. It is commonly used in sports field lighting, rural roadway lighting, and utility distribution on agricultural or municipal properties.
- baseball field lighting
- sports field lighting
- utility distribution
- rural roadway lighting
- area lighting
- parking lot lighting
- municipal lighting
- agricultural property lighting
The pole is designed for direct burial in soil and is suitable for locations where corrosion resistance, natural appearance, and structural strength are required. Not recommended for coastal or marine environments where salt exposure is present.
Installation and Long-Term Use
Direct burial installation requires excavation to a depth of 4 feet, with 16 feet of pole height above grade. Proper backfill and compaction are necessary to ensure stability and prevent settling. The pole can be field-drilled for mounting brackets, arms, or crossarms as needed for lighting or utility hardware.
Routine inspection is recommended to monitor for signs of decay, insect activity, or mechanical damage. Maintenance may include hardware tightening, surface treatment, or replacement of damaged components. The pole is compatible with standard lighting and utility mounting hardware designed for wood poles.
How This Fixture Is Commonly Used
Common mounting heights are 16 feet above grade, supporting area lighting, sports field fixtures, or utility lines. Fixture spacing and layout depend on the lighting design, field size, and required light levels. Poles are typically spaced to provide uniform coverage for sports fields or area lighting, or as required for utility distribution spans.
Higher mounting heights may require larger poles or additional engineering review for wind load and fixture weight. Using higher output fixtures can reduce the number of poles needed but may increase glare or require more robust mounting hardware.
Safety, Certifications, and Warranty
This pole is manufactured to ANSI O5.1 specification and treated to American Wood Preservers Association standards. CCA treatment provides resistance to decay, rot, and termites. The product includes a 1-year warranty covering material and workmanship.
Standard safety practices for pole handling, lifting, and installation apply. Use appropriate equipment and follow local codes for excavation, backfill, and electrical safety during installation and maintenance.
