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

Product Overview

This is a 15-foot square steel light pole with a 4-inch shaft width, designed for anchor base installation. 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 134 pounds.

The pole includes a 2 3/8-inch tenon for direct fixture mounting. The bolt circle measures 8 to 10 inches, with a bolt projection of 2.75 inches. This pole is intended for commercial and industrial exterior lighting applications where a medium-height steel pole with anchor base mounting is required.

Where This Product Fits Best

This 15-foot pole height works well for parking areas, walkways, building perimeters, and small lot applications where fixtures need to be positioned above vehicle and pedestrian traffic but do not require the reach of taller distribution poles. The 4-inch square profile provides a clean architectural appearance suitable for retail centers, office parks, and institutional properties.

The anchor base installation method requires a concrete foundation with embedded anchor bolts. This is standard practice for permanent pole installations where below-grade direct burial is not preferred or where soil conditions favor a poured foundation.

Performance and Functional Considerations

Wind load capacity is expressed in Effective Projected Area ratings across multiple wind speeds. At 70 mph, the pole supports an EPA of 15.2. At 90 mph, EPA drops to 11.1. At 110 mph, the rated EPA is 7.9, and at 120 mph, the pole supports 6.8 EPA.

These EPA values determine how much fixture area the pole can safely support at each wind speed. Fixture manufacturers publish EPA values for their products, and the combined EPA of all mounted fixtures must remain within the pole''s rated capacity for the site''s design wind speed.

The 11-gauge steel wall thickness and galvanized plus powder coated finish provide corrosion resistance for exterior exposure. Both bronze and white color options use the same base finish system.

Installation and Long-Term Use

Anchor base installation requires a pre-poured concrete foundation with anchor bolts set to the 8 to 10-inch bolt circle. Bolt projection is 2.75 inches, which determines the leveling nut range and base cover clearance. Foundation design must account for local frost depth, soil bearing capacity, and wind load transfer.

The included 2 3/8-inch tenon accepts slip-fitter style fixtures directly. Fixtures with tenon-mount adapters sized for 2 3/8-inch outside diameter will mount without modification. The pole weight of 134 pounds typically requires two people or mechanical assistance for safe handling and installation.

The galvanized and powder coated finish is designed for long-term exterior use. Periodic inspection of the base cover, anchor nuts, and finish condition is standard maintenance practice for steel poles in commercial installations.

How This Fixture Is Commonly Used

Facilities typically use this pole for area lighting where a 15-foot mounting height provides adequate coverage without over-lighting adjacent areas or creating excessive glare. The square profile is often selected for properties where architectural consistency matters, such as retail, hospitality, or campus environments.

The 2 3/8-inch tenon allows fixture changes or upgrades without pole replacement. When lighting needs change, compatible fixtures can be swapped directly onto the existing tenon. The bronze and white finish options allow matching to building trim, fencing, or other site elements.

Safety, Certifications, and Warranty

This pole carries a 1-year warranty. The warranty covers manufacturing defects in materials and workmanship under normal use conditions.

The hot dip galvanized base layer provides corrosion protection to the steel substrate. The powder coat finish adds color and additional surface protection. Both finish layers are applied at the factory.
