20 Foot Wood Pole | Class 4 | Treated | Southern Yellow Pine

Product Overview

We supply a 20 Foot Class 4 CCA Treated Southern Yellow Pine Wood Pole designed for direct burial installation in outdoor environments. This pole is manufactured to ANSI O5.1 specification and pressure treated to meet American Wood Preservers Association standards. Typical use includes supporting lighting or utility distribution in sports fields, rural roadways, and agricultural properties where wood poles are preferred for their non-conductive properties and ease of field modification.

The 20-foot length provides 16 feet above grade after 4 feet of burial, making it suitable for mounting area lights or utility lines at moderate heights. This pole is commonly specified for municipal, recreational, and utility applications where wood is required or preferred over steel or fiberglass alternatives.

Core Performance and Output

This Class 4 wood pole supports moderate wind loads and fixture weights typical for area lighting, sports field lighting, and utility distribution at 16 feet above grade. The minimum top circumference of 21 inches and 6.7-inch top outside diameter provide adequate strength for mounting single or double fixtures, small crossarms, or utility hardware.

CCA treatment protects against decay, termites, and rot, extending service life in outdoor and rural environments. Structural performance is suitable for standard area lighting heads, small sports field luminaires, and utility hardware within the pole?s weight and wind load limits. Excessive fixture weight or large sail area fixtures may require a higher class or larger diameter pole.

Adjustability and Control Options

Wood poles allow field drilling and hardware attachment for brackets, arms, or crossarms. Mounting locations can be adjusted on site to accommodate fixture aiming or utility hardware placement. The pole can accept a range of standard through-bolts, lag screws, and banding systems.

No integrated control options are provided with the pole. Controls and wiring are determined by the fixture or utility hardware installed. Field modifications should follow best practices to maintain structural integrity and preserve the CCA treatment at any cut or drilled locations.

Longevity and Reliability

Pressure treatment with CCA extends the service life of Southern Yellow Pine in outdoor environments, providing resistance to rot, decay, and insect damage. The pole is designed for direct burial, with a 4-foot embedment depth supporting stability and load transfer.

Routine inspection is recommended to monitor for mechanical damage, surface checking, or ground line decay over time. Service life is influenced by soil conditions, drainage, and exposure. The 1-year warranty covers manufacturing defects but does not extend to site-specific environmental factors.

Build Quality and Physical Characteristics

This pole is constructed from Southern Yellow Pine, debarked and pressure treated in the United States. It meets ANSI O5.1 requirements for Class 4 poles, with a weight range of 450?550 lbs. Minimum circumference and diameter specifications ensure consistent structural performance.

The pole is supplied with a clean, debarked surface and uniform treatment penetration. CCA treatment is suitable for most outdoor environments, but not for direct contact with potable water or food production areas. Field cuts or holes should be retreated with an approved preservative to maintain protection.

Where This Product Fits Best

This 20-foot Class 4 wood pole is suited for moderate-height outdoor lighting and utility distribution in sports, municipal, and rural environments. It is commonly used where wood is preferred for its non-conductivity, field adaptability, and traditional appearance.

• baseball field lighting
• sports field lighting
• utility distribution
• area lighting
• rural roadway lighting
• agricultural property lighting
• municipal lighting
• parking lot lighting

CCA treatment and direct burial installation make this pole suitable for wet, humid, or insect-prone environments. Not recommended for coastal or marine exposure without additional protection.

Installation and Long-Term Use

Direct burial installation requires a 4-foot embedment below grade, with tamped backfill for stability. The pole?s weight allows for handling with standard lifting equipment. Field drilling for hardware or fixture mounting is supported, but all cuts should be retreated with preservative.

Routine inspection at ground line and above grade is recommended to monitor for decay or mechanical damage. Service life is maximized with proper drainage and avoidance of standing water at the base. Hardware selection should match the pole?s structural capacity and avoid overloading the top section.

How This Fixture Is Commonly Used

Typical mounting height is 16 feet above grade, supporting area lights, sports field luminaires, or utility crossarms. Fixture spacing and layout depend on light level requirements and field geometry. Poles are often spaced 60?120 feet apart for sports fields or area lighting, with closer spacing for utility distribution.

Higher fixture weight or large sail area may require a higher class pole or reduced mounting height. Field adaptability allows for custom bracket placement, but excessive hardware concentration at the top can reduce structural performance.

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 and insects. The product carries a 1-year warranty against manufacturing defects.

Standard safety practices for lifting, handling, and installation apply. Use appropriate personal protective equipment and follow local codes for pole setting and grounding. Not rated for marine or corrosive environments without additional protection.

Frequently Asked Questions

Q: What is the maximum fixture weight this pole can support?

A: The Class 4 rating supports typical area lights, small sports field fixtures, or utility hardware. For large or heavy fixtures, verify total weight and wind load against the pole?s structural limits.

Q: Can this pole be used for double fixture mounting?

A: Yes, double fixture mounting is possible within the pole?s weight and wind load capacity. Use appropriate brackets and hardware, and avoid excessive loading at the top section.

Q: Is this pole suitable for coastal or marine environments?

A: Standard CCA treatment is not recommended for direct marine or coastal exposure. For those environments, consider poles with additional protection or alternative materials.

Q: What is the recommended spacing for sports field lighting with this pole?

A: Spacing typically ranges from 60 to 120 feet, depending on light level requirements and fixture output. Adjust spacing based on field size and lighting design.

Q: How should field-drilled holes or cuts be treated?

A: All field cuts or drilled holes should be treated with an approved wood preservative to maintain decay and insect resistance.

Application Questions and Clarification

Q: Is this pole appropriate for utility distribution in rural areas?

A: Yes, this pole is commonly used for utility distribution in rural and agricultural settings where wood is preferred for its non-conductivity and field adaptability.

Q: Can this pole be used for parking lot lighting?

A: This pole is suitable for parking lot lighting at moderate mounting heights, supporting standard area light fixtures within its structural limits.

Q: What is the typical above-grade height after installation?

A: After direct burial, the pole provides 16 feet above grade for fixture or hardware mounting.

Q: Does this pole meet ANSI and AWPA standards?

A: Yes, the pole is manufactured to ANSI O5.1 specification and treated to American Wood Preservers Association standards.
