20 Foot Square Steel Light Pole | 4 Inches Wide | Anchor Base

Product Overview

This is a 20-foot square steel light pole with a 4-inch width and anchor base mounting configuration. The pole is constructed from 11-gauge steel with a hot dip galvanized and powder coated finish, available in bronze or white. Total pole weight is 169 pounds.

The pole includes a 2 3/8-inch tenon for fixture mounting. The bolt circle measures 8 to 10 inches with a bolt projection of 2.75 inches. This pole carries a 1-year warranty.

Where This Product Fits Best

A 20-foot pole height is appropriate for parking areas, pathways, building perimeters, and similar applications where moderate mounting height is needed. The 4-inch square profile and 11-gauge wall thickness provide structural capacity for typical area lighting fixtures within the published EPA limits.

The anchor base installation requires a concrete foundation with embedded anchor bolts matching the 8 to 10-inch bolt circle. This pole is suited to permanent installations where the foundation can be poured or already exists with compatible bolt spacing.

Performance and Functional Considerations

Wind load capacity is expressed in Effective Projected Area ratings across wind speed ranges. At 70 mph, the pole supports up to 10.2 square feet EPA. At 90 mph, this drops to 7.5 square feet. At 110 mph, the rating is 4.2 square feet, and at 120 mph the maximum is 3.6 square feet.

These EPA values determine which fixtures and mounting arms the pole can safely support under wind load conditions. Fixture EPA ratings must fall within the pole''s capacity at the design wind speed for the installation site.

Installation and Long-Term Use

The anchor base mounts to a concrete foundation using anchor bolts positioned on an 8 to 10-inch bolt circle. Bolt projection is 2.75 inches. Foundation design and anchor bolt sizing must account for pole height, fixture weight, and local wind conditions.

The hot dip galvanized and powder coated finish provides corrosion resistance for outdoor exposure. The included 2 3/8-inch tenon accepts slip-fitter style fixture mounts directly without adapters.

How This Fixture Is Commonly Used

The 2 3/8-inch tenon at the top of the pole accepts standard slip-fitter mounted fixtures. This allows fixtures to be aimed or repositioned on the tenon during installation to direct light where needed. Once set, the fixture is secured in place with set screws.

At 169 pounds, this pole typically requires mechanical assistance or a crew for handling and installation. The square profile provides a clean appearance for commercial properties, retail lots, and campus environments where pole aesthetics are considered.

Safety, Certifications, and Warranty

This pole is covered by a 1-year warranty. The hot dip galvanized and powder coated finish meets standard outdoor durability expectations for steel poles in commercial applications.

Foundation and anchor bolt design must comply with local building codes and wind load requirements. EPA ratings provided should be matched against fixture specifications and site-specific design wind speeds.
