55 Foot Wood Pole | Class 4 | Treated | Southern Yellow Pine
This 55 foot Class 4 Southern Yellow Pine utility pole is a solid choice for outdoor lighting and distribution projects requiring significant above-ground clearance and moderate cross-arm loading. Its CCA treatment protects against rot and decay, making it reliable for direct burial in environments with ground contact and moisture exposure. The pole supports 2 to 4 cross-arms with up to 240 pounds of load, accommodating multiple fixtures or lines as needed. Manufactured to ANSI O5.1 standards, it is well-suited for roadways, industrial yards, and large commercial sites where durability and stable elevated mounting are essential.

Our 55 foot Class 4 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 treated with preservatives to the latest American Wood Preservers Association standards to ensure rot and decay prevention. The long term durability of a wood utility pole is one of its main benefits
Cross arms are available for our Southern Yellow Pine poles as an optional accessory. Configuration and sizing are determined based on project requirements, as well as the height and class of the selected pole. We offer both 8-foot and 10-foot cross arms, our product specialists can help confirm the appropriate size for your application.
Delivery is made with a standard flatbed truck depending on pole lengths and the customer is responsible for offloading. Offloading requires a fork lift or appropriate similar vehicle to offload - customer supplied. Customer is responsible for any costs associated with delivery rescheduling because of improper scheduling or not having the proper offloading equipment available at time of delivery. Installation should be done by a trained professional.
Pricing: Does not include price 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 55 foot Class 4 wood pole is manufactured from Southern Yellow Pine and treated with CCA preservative. It is designed for direct burial installation in outdoor environments where structural height and durability are required. Typical use includes supporting sports field lighting and utility distribution in municipal, rural, and recreational settings.
The pole meets ANSI O5.1 standards and is produced to American Wood Preservers Association specifications for rot and decay resistance. With a total length of 55 feet and a height above grade of 47.5 feet, this pole is suitable for large-scale lighting and utility projects where elevated mounting is necessary.
Core Performance and Output
This Class 4 wood pole supports mounting heights up to 47.5 feet above grade, providing the elevation needed for sports field lighting and utility lines. The pole’s structural capacity is determined by its class, diameter, and wood species, supporting typical fixture loads and cross arm assemblies for its application range. Minimum top circumference is 21 inches, with a 6.7 inch minimum top outside diameter, ensuring compatibility with standard mounting hardware.
Wind load and EPA (Effective Projected Area) performance are consistent with Class 4 wood pole standards. Actual fixture and cross arm loading must be verified against site-specific wind conditions and total EPA. Excessive fixture weight or large sail area may require higher class or larger diameter poles for compliance.
Adjustability and Control Options
This pole is supplied as a fixed-length, direct burial wood structure. Height above grade is determined by the specified burial depth of 7.5 feet. Cross arms are available as optional accessories in 8-foot and 10-foot lengths, allowing for project-specific configuration of luminaires or utility hardware.
No integrated electrical or control features are included. All wiring, controls, and fixture mounting hardware must be specified and installed separately according to project requirements and local codes.
Longevity and Reliability
Southern Yellow Pine is selected for its strength and durability in outdoor structural applications. CCA treatment provides resistance to rot, decay, and insect activity, supporting long-term performance in exposed environments. Compliance with ANSI O5.1 and AWPA standards ensures consistent quality and service life.
Routine inspection and maintenance are recommended to monitor for physical damage, wood checking, or ground line decay over time. Actual service life will vary based on soil conditions, climate, and loading.
Build Quality and Physical Characteristics
This pole is manufactured in the United States from debarked Southern Yellow Pine. It weighs between 1785 and 2100 lbs, with a minimum circumference of 38 inches measured 6 feet from the butt. The pole is treated with CCA preservative to AWPA standards for outdoor use.
Direct burial installation requires excavation to a depth of 7.5 feet. The pole’s dimensions and taper are compatible with standard cross arms, brackets, and utility hardware. Optional cross arms are available for lighting or utility distribution applications.
Where This Product Fits Best
This 55 foot Class 4 wood pole is suited for large outdoor environments requiring elevated mounting for lighting or utility distribution. It is commonly used in sports field lighting, municipal utility projects, and rural area installations where direct burial and wood construction are preferred.
- baseball field lighting
- football field lighting
- sports field lighting
- utility distribution
- area lighting
- municipal lighting
- parking lot lighting
- agricultural property lighting
CCA treatment and Southern Yellow Pine construction provide durability in outdoor, rural, and recreational settings. The pole is suitable for locations where direct burial is feasible and where wood poles are standard practice.
Installation and Long-Term Use
Direct burial installation requires excavation to the specified depth, with backfill and compaction according to local standards. The pole’s weight and length require equipment for handling and placement. Cross arms and hardware must be installed per project requirements and verified for load compatibility.
Long-term use depends on soil drainage, exposure, and maintenance. Periodic inspection at the ground line and above grade is recommended to monitor for decay or mechanical damage. Replacement or reinforcement may be required if significant deterioration is observed over time.
How This Fixture Is Commonly Used
Typical mounting height above grade is 47.5 feet, supporting elevated lighting or utility lines for sports fields and large outdoor areas. Fixture spacing and cross arm configuration are determined by lighting design or utility requirements. Poles are often spaced to provide uniform coverage for fields or to support distribution lines across open areas.
Higher mounting heights reduce the number of poles needed for large fields but may require larger fixtures or higher wattage to achieve target light levels. EPA and wind loading must be considered when specifying fixture quantity and arrangement.
Safety, Certifications, and Warranty
This pole is manufactured to ANSI O5.1 standards and treated to American Wood Preservers Association specifications. CCA treatment provides resistance to rot and decay for outdoor use. The product includes a 1-year warranty covering manufacturing defects.
All installation and use must comply with local codes and safety standards. Proper handling and lifting procedures are required due to the pole’s weight and length.
