Product Overview

This is a 20-foot square steel light pole with a 4-inch width and anchor base mounting. The pole is constructed from 11-gauge steel and weighs 169 pounds. It is finished with a hot-dip galvanized coating and powder coat in either bronze or white.

The pole includes a 2 3/8 inch tenon for fixture mounting. The anchor base design uses an 8-inch bolt circle and a 2.75-inch bolt projection. This pole is designed for commercial-grade exterior lighting applications.

Where This Product Fits Best

This 20-foot steel pole is suitable for outdoor lighting in parking lots, perimeter areas, drive lanes, and general site lighting where a 20-foot mounting height is required. The 4-inch square profile supports a range of area and flood lighting fixtures.

It is appropriate for installations where wind load and EPA requirements must be considered, such as open lots, campuses, and commercial properties. The hot-dip galvanized and powder-coated finish provides durability in environments exposed to weather and moisture.

Performance and Functional Considerations

The pole is rated for effective projected area (EPA) loads up to 10.2 at 70 mph and 3.6 at 120 mph. This allows for fixture mounting in locations with varying wind conditions, provided the total EPA of fixtures and accessories does not exceed these values.

The 2 3/8 inch tenon supports standard slipfitter and bracket-mounted fixtures. The 11-gauge steel construction provides structural strength for commercial and industrial use. The anchor base design allows for secure installation on concrete foundations.

Installation and Long-Term Use

The anchor base mounting requires a concrete foundation with an 8-inch bolt circle and 2.75-inch bolt projection. The pole is delivered with a hot-dip galvanized and powder-coated finish for corrosion resistance and long-term durability.

Color options in bronze or white allow for visual coordination with site requirements. The 20-foot height and 4-inch width provide compatibility with a range of area lighting fixtures and accessories using the included tenon.

How This Fixture Is Commonly Used

After installation, this pole is used to support area lights, flood lights, or other exterior fixtures at a 20-foot mounting height. The 2 3/8 inch tenon allows for direct attachment of slipfitter-mounted fixtures without additional adapters.

Operators can select fixture combinations that remain within the EPA limits for their site wind conditions. The galvanized and powder-coated finish reduces maintenance requirements by protecting against rust and surface wear.

Routine inspection of the anchor base and hardware is recommended to ensure ongoing structural integrity, especially in high-traffic or exposed environments.

Safety, Certifications, and Warranty

This pole is constructed from 11-gauge steel and finished with hot-dip galvanizing and powder coating for corrosion resistance. The anchor base design provides secure mounting when installed according to specifications.

LED Lighting Supply provides a 1-year warranty on this pole.
