15 Foot Above Grade | 18 Foot Total Height Square Steel Light Pole | 4 Inches Wide | Direct Burial

Product Overview

This is an 18-foot total height, 4-inch wide square steel light pole designed for direct burial installation. The pole provides 15 feet of height above grade, with 3 feet set below ground for stability. It is constructed from 11-gauge steel, hot dip galvanized and powder coated for corrosion resistance. A 2 3/8 inch tenon is included for fixture mounting. This pole is commonly used for supporting area, parking lot, and roadway lighting fixtures in commercial and industrial environments.

Direct burial installation eliminates the need for anchor bolts and base plates, streamlining installation in new construction or site upgrades. The pole?s finish and material selection are intended for long-term outdoor use in environments where durability and structural integrity are required.

Core Performance and Output

This pole supports fixtures with a combined Effective Projected Area (EPA) up to 15.2 at 70 mph, decreasing to 3.8 at 140 mph. The 4-inch square profile and 11-gauge steel construction provide structural capacity for typical area, parking lot, and roadway lighting heads. The included 2 3/8 inch tenon is compatible with most standard slipfitter and bracket-mounted luminaires.

Performance is dependent on wind loading and fixture EPA. Exceeding EPA ratings at site wind speeds can compromise pole stability. At the 15-foot mounting height, this pole is suitable for single or dual fixture configurations within EPA and weight limits. Excessive fixture weight or large arrays may require a larger pole section or reduced mounting height.

Adjustability and Control Options

The pole includes a 2 3/8 inch tenon for mounting slipfitter or bracket-style fixtures. This allows for horizontal and vertical aiming adjustments at the fixture level, depending on the luminaire design. The pole itself is fixed once installed and does not provide telescoping or tilt adjustment.

Control options such as photocells, motion sensors, or wireless nodes are determined by the fixture and accessory selection, not the pole. The pole accommodates standard wiring practices for exterior lighting circuits routed through the pole shaft.

Longevity and Reliability

The pole is fabricated from 11-gauge steel and finished with hot dip galvanizing followed by a powder coat. This combination provides resistance to corrosion, abrasion, and weathering in outdoor environments. Direct burial installation requires proper site preparation and backfill to prevent premature corrosion at the ground line.

Routine inspection for finish integrity and straightness is recommended, especially in high-traffic or high-wind areas. The pole is designed for long-term structural performance when installed according to standard practices and within EPA and weight limits.

Build Quality and Physical Characteristics

This pole measures 18 feet in total length, with 15 feet above grade and 3 feet below grade. The 4-inch square cross-section and 11-gauge wall thickness provide rigidity and resistance to bending. The pole weighs 121 lbs and is finished in bronze.

The hot dip galvanized and powder coated finish protects against rust and surface damage. The direct burial design eliminates the need for a base plate, reducing installation hardware and potential points of failure. The included tenon is welded and sized for standard area and roadway fixtures.

Where This Product Fits Best

This pole is intended for outdoor environments requiring reliable support for area, parking lot, and roadway lighting at moderate mounting heights. It is suitable for commercial, municipal, and industrial sites where direct burial installation is preferred or required.

• parking lot lighting
• roadway lighting
• area lighting
• commercial site lighting
• sports facility lighting
• campus lighting
• industrial yard lighting
• dealership lighting

The pole?s finish and material selection are appropriate for most climates, including regions with moderate to high humidity. Not intended for coastal or marine environments without additional corrosion protection.

Installation and Long-Term Use

Direct burial installation requires excavation to a minimum depth of 3 feet, with proper backfill and compaction for stability. The pole shaft allows for internal wiring, with access provided at the base or through handhole provisions if specified. The 2 3/8 inch tenon supports standard slipfitter and bracket-mounted fixtures.

Routine maintenance includes inspection for corrosion at the ground line, checking for pole plumbness, and verifying fixture attachment hardware. In regions with high wind exposure, periodic review of EPA and fixture configuration is recommended to maintain compliance with structural ratings.

How This Fixture Is Commonly Used

This pole is typically installed at 15 feet above grade, supporting one or two area or roadway fixtures per pole. Spacing between poles varies based on fixture output, site layout, and required light levels, but is commonly 2 to 4 times the mounting height for uniform coverage in parking lots or along roadways.

Higher output fixtures can increase pole spacing but may introduce glare or require careful aiming. Fixture selection and EPA must remain within the pole?s rated limits for wind and weight.

Safety, Certifications, and Warranty

The pole is manufactured from structural steel and finished with hot dip galvanizing and powder coating. EPA ratings are provided for wind speeds from 70 to 140 mph. The product includes a 1-year warranty.

All installation and use must comply with local codes and standards for structural supports and outdoor lighting systems.

Frequently Asked Questions

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

A: The maximum EPA is 15.2 at 70 mph, decreasing to 3.8 at 140 mph. Always verify site wind speed and total fixture EPA before installation.

Q: What is the recommended burial depth for this pole?

A: The pole is designed for 3 feet of burial below grade, resulting in 15 feet above grade.

Q: What type of fixtures can be mounted to the included tenon?

A: The 2 3/8 inch tenon is compatible with most slipfitter and bracket-mounted area, parking lot, and roadway fixtures.

Q: Can this pole be used in coastal or marine environments?

A: This pole is not intended for coastal or marine environments without additional corrosion protection.

Q: How should I plan pole spacing for parking lot lighting?

A: Typical spacing is 2 to 4 times the mounting height, depending on fixture output and site requirements. Confirm with a lighting layout for uniformity and coverage.

Application Questions and Clarification

Q: Is this pole suitable for sports facility lighting at 15 feet?

A: Yes, for small-scale sports facility lighting where mounting heights and fixture EPA are within the pole?s rated limits.

Q: Can this pole be used for industrial yard lighting?

A: Yes, provided the fixture configuration does not exceed EPA and weight ratings for the site wind speed.

Q: Is this pole compatible with campus or dealership lighting applications?

A: Yes, this pole is commonly used for campus and dealership lighting at moderate mounting heights.

Q: What are the limitations for area lighting applications?

A: The main limitations are fixture EPA, total weight, and wind speed at the site. Exceeding these can compromise structural integrity.
