20 Foot Wood Pole | Class 6 | Treated | Ponderosa Pine

Product Overview

This 20 Foot Wood Pole, Class 6, is manufactured from Ponderosa Pine and treated with CCA preservative. It is designed for use as a light pole or utility pole in outdoor environments where direct burial installation is required. The pole provides 16 feet of height above grade, with a 4-foot section below grade for stability and structural support.

Typical use includes supporting lighting fixtures or utility lines in sports fields, rural roadways, agricultural properties, and municipal sites. The pole meets ANSI O5.1 standards and is suitable for installations where wood is preferred for its non-conductive properties and ease of handling compared to steel or concrete alternatives.

Core Performance and Output

This Class 6 wood pole supports light to moderate loads, with a typical weight range of 200?300 lbs and minimum top circumference of 17 inches. The structural capacity is appropriate for mounting single or double lighting fixtures, small area floodlights, or utility distribution hardware within the pole?s EPA and weight limits. The 16-foot above-grade height is suitable for low to mid-mounting applications, such as small sports fields or rural area lighting.

Direct burial installation provides stable support in soil, but actual load capacity depends on soil conditions and installation depth. Excessive fixture weight or large sail area (EPA) may exceed the pole?s structural limits. Not recommended for high-mast or large multi-fixture arrays.

Adjustability and Control Options

This wood pole does not include integrated adjustability or control features. Fixture mounting locations and hardware are determined by field installation requirements. Drilling for arm brackets, crossarms, or tenons is performed on-site or specified prior to delivery.

Control systems, such as photocells or wireless controls, are supported through compatible fixtures or external mounting. The pole itself does not restrict the use of standard lighting controls or utility hardware.

Longevity and Reliability

The pole is pressure treated with CCA to resist termites, decay, and rot. This extends service life in outdoor environments, including areas with high moisture or ground contact. Ponderosa Pine provides a balance of strength and workability for field modifications or hardware attachment.

Long-term reliability depends on installation quality, soil drainage, and periodic inspection for physical damage or surface degradation. Direct ground contact may eventually lead to base deterioration if drainage is poor or if the pole is exposed to standing water for extended periods.

Build Quality and Physical Characteristics

Each pole is manufactured to ANSI O5.1 standards, ensuring consistent dimensions and structural performance. The minimum circumference at the top is 17 inches, with 23 inches measured 6 feet from the butt. The outer diameter at the top is 5.4 inches, increasing to 7.32 inches at the base section.

Ponderosa Pine is selected for straightness and uniformity. The CCA treatment is applied to meet American Wood Preservers Association standards. The pole is supplied debarked and ready for direct burial installation. Weight varies by individual pole but falls within the 200?300 lb range for this class and length.

Where This Product Fits Best

This 20-foot Class 6 wood pole is suited for outdoor environments where moderate mounting height and non-conductive support are required. It is commonly used in sports field lighting, rural area lighting, and utility distribution where wood poles are standard practice.

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

The pole is suitable for direct burial in soil and can be used in both public and private installations. CCA treatment provides resistance to decay and insect attack in most climates.

Installation and Long-Term Use

Direct burial installation requires a 4-foot embedment below grade, leaving 16 feet above ground for fixture or hardware mounting. Standard practice is to set the pole in compacted soil or gravel backfill for stability. Installation equipment must accommodate the 200?300 lb pole weight and 20-foot length.

Periodic inspection is recommended to monitor for surface damage, decay at ground line, or hardware loosening. Replacement cycles depend on site conditions and maintenance practices. Field drilling for brackets or arms should avoid excessive removal of wood at critical load points.

How This Fixture Is Commonly Used

Poles of this size are typically installed at 16?20 foot mounting heights for single or double lighting fixtures, small area floodlights, or utility lines. Spacing between poles varies based on light level requirements, fixture wattage, and field layout. For sports fields, poles are often placed along perimeters or at corners to provide uniform coverage.

Using higher output fixtures can reduce the number of poles required but may increase wind load and structural demand on each pole. Careful evaluation of fixture EPA and total weight is necessary to avoid exceeding the pole?s rated capacity.

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 termites, decay, and rot. The product carries a 1-year warranty from the date of installation.

Standard safety practices for wood pole installation apply, including proper lifting, handling, and ground preparation. The pole is non-conductive, reducing electrical hazard risk compared to metal poles in certain applications.

Frequently Asked Questions

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

A: The Class 6 rating and 20-foot length are suitable for light to moderate fixture loads. Always verify total fixture weight and EPA with structural guidelines for Class 6 wood poles.

Q: Can this pole be used for double arm or crossarm lighting?

A: Yes, provided the combined weight and wind load do not exceed the pole?s structural limits. Field drilling for arms is common but should be performed according to best practices.

Q: Is this pole suitable for coastal or high-moisture environments?

A: The CCA treatment provides resistance to decay and insects, but long-term performance in coastal or saturated soils may require additional inspection and maintenance.

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

A: Spacing depends on fixture wattage, beam spread, and field size. Typical layouts for small fields use 4?8 poles per field, but site-specific photometric analysis is recommended.

Application Questions and Clarification

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

A: Yes, for small parking lots or perimeter lighting where mounting height and fixture load are within Class 6 limits.

Q: Is this pole appropriate for utility distribution lines?

A: Yes, this pole is commonly used for light utility distribution in rural or municipal settings.

Q: What is the minimum burial depth required?

A: The pole is designed for 4 feet of burial below grade, leaving 16 feet above ground.

Q: Are there restrictions on fixture EPA or sail area?

A: Yes, ensure total EPA and wind load do not exceed Class 6 pole ratings. Consult structural tables for maximum allowable EPA at 20-foot length.
