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 5 CCA Treated Southern Yellow Pine Pole is designed for use as a light pole or utility pole in outdoor environments. It is manufactured from Southern Yellow Pine, pressure treated with CCA preservative, and meets ANSI O5.1 standards for structural wood poles. Typical installations include direct burial for area lighting, sports field lighting, and utility distribution in municipal, rural, and recreational settings. The 20-foot length and Class 5 rating make it suitable for mounting luminaires or supporting overhead lines at moderate heights.
Direct burial installation is standard, with 4 feet below grade and 16 feet above grade. The pole is commonly specified for new construction or replacement projects where wood is preferred for its non-conductive properties and natural appearance. Weight ranges from 400 to 500 lbs depending on moisture content and specific dimensions.
Core Performance and Output
This pole supports typical area and sports lighting fixtures, as well as utility distribution hardware, within the structural limits of a Class 5 wood pole. Minimum top circumference is 19 inches, with a 6-inch minimum top outside diameter. At 6 feet from the butt, the circumference is at least 23 inches and the outside diameter is 7.3 inches. The pole is rated for moderate wind loads and fixture EPAs consistent with its class and height.
Class 5 rating provides adequate strength for mounting single or double luminaires, small crossarms, or light utility loads. Excessive fixture weight or large sail area may exceed structural limits, especially in high wind zones. For heavier or higher EPA fixtures, a higher class or taller pole may be required.
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 to suit project requirements. Hardware for luminaire arms, crossarms, or brackets must be specified separately and installed according to manufacturer and code requirements.
Control systems such as photocells, wireless nodes, or utility metering can be mounted externally. There are no internal wiring channels; all conduit or cabling must be surface-mounted or routed externally as per standard wood pole practice.
Longevity and Reliability
The pole is pressure treated with CCA to resist termites, decay, and rot. Service life depends on soil conditions, climate, and installation quality. In typical outdoor environments, treated Southern Yellow Pine poles provide reliable structural support for many years.
Periodic inspection for mechanical damage, decay at ground line, and hardware corrosion is recommended. Direct burial installation requires proper backfill and compaction to maintain pole stability over time.
Build Quality and Physical Characteristics
Each pole is manufactured from Southern Yellow Pine, debarked, and treated in the United States. The wood is selected for structural integrity and uniformity. CCA treatment is applied to meet American Wood Preservers Association standards.
Poles are supplied with a natural wood finish. Dimensions and weight may vary slightly due to wood species and moisture content. The pole is non-conductive and suitable for use in electrical distribution and lighting support applications.
Where This Product Fits Best
This 20-foot Class 5 wood pole is suited for outdoor lighting and utility support in sports, municipal, and rural environments. It is commonly used where moderate mounting heights are required and wood is preferred for its electrical and environmental properties.
- baseball field lighting
- sports field lighting
- utility distribution
- area lighting
- parking lot lighting
- municipal lighting
- agricultural property lighting
- rural roadway lighting
CCA treatment provides resistance to decay and insect damage. The pole is suitable for direct burial in a range of soil types. Not recommended for coastal or marine environments without additional protection.
Installation and Long-Term Use
Direct burial installation requires excavation to a depth of 4 feet, with 16 feet remaining above grade. Proper tamping and backfill are critical for long-term stability. Standard pole setting equipment is required due to the 400?500 lb weight.
Mounting hardware for luminaires, crossarms, or utility equipment must be compatible with wood construction. Periodic inspection at the ground line is recommended to monitor for decay or mechanical damage. Replacement cycles are determined by site conditions and inspection findings.
How This Fixture Is Commonly Used
Typical mounting height above grade is 16 feet, supporting single or double luminaires, small crossarms, or utility lines. Spacing between poles varies based on lighting layout, fixture wattage, and required light levels for the application.
In sports field or area lighting, poles are often spaced to provide uniform coverage and minimize shadows. For utility distribution, spacing is determined by line tension and sag requirements. Higher fixture EPA or heavier loads may require reduced spacing or higher class poles.
Tradeoff: Using higher output luminaires on this pole may reduce the number of poles needed, but can increase wind loading and structural stress. Always verify fixture EPA and weight against pole class and local wind codes.
Safety, Certifications, and Warranty
This pole is manufactured to ANSI O5.1 standards. CCA treatment meets American Wood Preservers Association requirements. The product is non-conductive and suitable for use in electrical and lighting support applications.
Warranty is 1 year. Follow all local codes and standards for installation and grounding. Inspect hardware and pole condition periodically to maintain safety and performance.
