Our 20 Foot Class 6 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 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 is a 20 foot wood pole manufactured from Southern Yellow Pine. The pole is treated with CCA preservative and meets ANSI Class 6 requirements. It is designed for direct burial installation with a 4 foot burial depth below grade, leaving 16 feet above grade for mounting equipment.
The pole weighs between 300 and 400 pounds, with a minimum top circumference of 17 inches and a minimum circumference of 21 inches measured 6 feet from the butt. The minimum pole top outside diameter is 5.4 inches, and the outside diameter 6 feet from the butt is 6.7 inches.
This pole is suitable for supporting up to two crossarms. It is intended for use in utility and lighting applications where a treated wood pole is required.
Where This Product Fits Best
This 20 foot Class 6 Southern Yellow Pine pole is used in outdoor environments where direct burial wood poles are standard practice. Typical applications include supporting area lighting, utility lines, or site infrastructure in commercial, industrial, or municipal settings.
The CCA treatment allows the pole to be installed in locations where resistance to decay, rot, and termite damage is required. The pole is suitable for installations where a 16 foot above-grade height is needed for mounting fixtures or equipment.
It is commonly selected for projects where wood poles are preferred over steel or concrete due to site conditions, aesthetic requirements, or compatibility with existing infrastructure.
Performance and Functional Considerations
The pole is manufactured to ANSI O5.1 specification and is classified as Class 6. This classification defines the minimum strength and dimensional requirements for the pole.
CCA treatment provides long-term resistance to decay and insect damage, supporting reliable performance in outdoor environments. The pole supports up to two crossarms, which is relevant for both lighting and utility applications.
Direct burial installation is required, with a specified 4 foot depth below grade. The pole's weight and dimensions should be considered for handling and installation planning.
Installation and Long-Term Use
This pole is designed for direct burial installation. A 4 foot burial depth is required to achieve the specified 16 feet of height above grade. Proper site preparation and equipment are needed to handle the 300-400 pound weight during installation.
Once installed, the CCA treatment protects the wood from rot, decay, and termite damage. The pole is suitable for long-term outdoor use in a range of climates and soil conditions, provided installation follows standard practices for wood utility poles.
The pole can accommodate up to two crossarms for mounting lighting fixtures or utility hardware. Maintenance requirements are typical for treated wood poles and depend on site-specific conditions.
How This Fixture Is Commonly Used
After installation, this 20 foot wood pole is used to support area lighting fixtures, utility lines, or other equipment that requires elevation above grade. The 16 foot above-grade height allows for effective mounting of luminaires or electrical hardware.
Facility operators typically interact with the pole during fixture maintenance or when adding or replacing crossarms. The treated wood construction provides durability in outdoor environments, reducing the need for frequent inspection or replacement due to decay or insect damage.
The pole's dimensions and strength class support reliable operation in standard commercial and industrial settings. The direct burial design streamlines installation and minimizes the need for additional mounting hardware.
