Our 20 Foot Class 5 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.

Our 20 ft round wood poles are perfect for sports fields, baseball fields, and a utility pole project. You can add 1 light arms per side, 2 in total. Each arm can accommodate 240 lbs of lights per arm. Availability can change based on the quantity and length required as different sizes can have different lead times. Our poles are built with durability in mind to ensure long-lasting performance.

Options Available:

Cross Arms (2 per pole, 1 per side) and Mounting Brackets. Customer is responsible for mounting Cross Arm after poles are delivered. Poles do not ship with cross arms attached.

These are the lights we typically mount on the cross arms. Up to 6 lights per arm, not to exceed 240 total pounds of fixtures and hardware.


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-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 Class 5 wood utility pole made from Southern Yellow Pine, pressure treated with CCA preservative. The pole is manufactured to ANSI O5.1 specification and meets American Wood Preservers Association standards for preservative treatment.

Total pole height is 20 feet, with 16 feet above grade and 4 feet buried below grade. The pole weighs between 400 and 500 pounds and is designed for direct burial installation without a concrete foundation.

Minimum circumference at the pole top is 19 inches, with a minimum diameter of 6 inches. At 6 feet from the butt, minimum circumference is 23 inches and minimum diameter is 7.3 inches. These dimensions follow ANSI Class 5 specifications.

Where This Product Fits Best

This pole is sized for applications requiring 16 feet of usable height above grade. Sports fields and baseball fields are common installations where this pole height and load capacity align with typical lighting requirements.

The CCA treatment protects the wood against termites, decay, and rot, making this pole suitable for permanent outdoor installation in ground contact. Direct burial installation eliminates the need for a separate concrete foundation.

Performance and Functional Considerations

The pole accepts a maximum of 2 cross arms total, with 1 cross arm permitted per side. Each cross arm supports up to 240 pounds of attached weight, which includes fixtures and mounting hardware combined.

Class 5 designation under ANSI O5.1 defines the structural capacity of this pole. The taper from butt to top follows standardized dimensions that determine load handling characteristics at the specified burial depth and above-grade height.

Cross arms are available as separate options and must be attached on site after pole delivery. Poles ship without cross arms installed.

Installation and Long-Term Use

Installation method is direct burial at 4 feet below grade. The 400 to 500 pound weight requires appropriate equipment for handling and setting. The buried section relies on the CCA treatment to resist ground-contact deterioration.

Mounting brackets are available for attaching cross arms to the pole. The installer is responsible for cross arm attachment and alignment after the pole is set.

The preservative treatment addresses the primary failure modes for wood poles in outdoor use: termite damage, fungal decay, and rot. These conditions are managed by the pressure treatment process applied before the pole ships.

How This Fixture Is Commonly Used

After installation, each cross arm position supports up to 6 light fixtures, provided the total weight of fixtures and hardware does not exceed 240 pounds per arm. This defines the practical upper limit for fixture quantity and size on each arm.

The 16-foot above-grade height establishes the mounting elevation for attached fixtures. This height is fixed by the pole length and burial depth and cannot be adjusted after installation.

With 2 cross arms permitted and 1 per side, lighting can be oriented in opposite directions from the pole. Fixture aiming and arm positioning are determined during installation and cross arm attachment.

Safety, Certifications, and Warranty

This pole is manufactured to ANSI O5.1 specification. Preservative treatment meets American Wood Preservers Association standards.

The poles are grown, debarked, and treated in the United States.

This product carries a 1-year warranty.
