Product Overview

This is a 20 foot fiberglass flag pole with a 5.75 inch base diameter and an internal halyard system. The pole is finished in white and weighs 41 pounds. It is designed for use with an anchor base installation method.

The pole features an internal cam cleat for halyard management and is rated to withstand wind speeds up to 125 mph when unflagged. The standard flag size for this pole is 4 x 6 feet. The tip outside diameter is 3 inches, and the ground-level outside diameter is 5.75 inches.

The base dimensions are 9 by 9 inches, with a bolt circle of 8 to 9 inches. The recommended anchor bolts are 24 inches long with a 3/4 inch diameter. Anchor bolts and base cover are not included.

This flag pole includes a 6 inch diameter ball at the top and uses a #10 (5/16 inch) halyard. The product carries a 15 year warranty from LED Lighting Supply.

Where This Product Fits Best

This 20 foot fiberglass flag pole is suitable for both commercial and residential outdoor installations where a durable, corrosion-resistant pole is required. The white finish and fiberglass construction make it appropriate for locations where aesthetics and long-term appearance are important.

With a 125 mph wind rating (unflagged), this pole is designed for areas that experience high wind conditions. It is commonly used at schools, municipal buildings, corporate campuses, and residential properties seeking a professional-grade flag display.

The anchor base installation method is intended for permanent mounting on concrete foundations or similar stable surfaces. The internal halyard system is preferred in applications where tamper resistance and a clean appearance are priorities.

Performance and Functional Considerations

The fiberglass construction provides resistance to corrosion and minimizes maintenance requirements compared to metal poles. The 125 mph wind rating (unflagged) supports use in exposed or coastal environments where wind loads are a concern.

The internal cam cleat halyard system keeps the rope protected inside the pole, reducing wear and minimizing noise from wind. The 5.75 inch ground-level outside diameter and 9 x 9 inch base provide a stable footprint for the 20 foot height.

The pole is designed to accommodate a standard 4 x 6 foot flag. The 6 inch ball at the top serves as a finial and helps prevent halyard abrasion.

Installation and Long-Term Use

This flag pole is installed using an anchor base system. The base requires a bolt circle of 8 to 9 inches and uses 24 inch long, 3/4 inch diameter anchor bolts. Anchor bolts and base cover are not included and must be provided separately.

The fiberglass material is non-conductive and does not rust, which reduces long-term maintenance. The internal halyard system is accessed through the pole and secured with an internal cam cleat, limiting unauthorized access and extending halyard life.

Routine inspection of the halyard and cleat is recommended to ensure smooth operation. The pole's 15 year warranty supports long-term use in demanding environments.

How This Fixture Is Commonly Used

After installation, the internal halyard system allows you to raise and lower the flag without external ropes. The cam cleat holds the halyard securely inside the pole, reducing the risk of tampering and keeping the appearance clean.

The fiberglass construction means you do not need to address rust or corrosion, even in coastal or high-humidity locations. The pole can be cleaned with standard non-abrasive methods as needed to maintain its appearance.

The 20 foot height and 4 x 6 foot flag size provide a visible display suitable for most commercial and residential settings. The 6 inch ball finial at the top is fixed and does not require adjustment after installation.

Safety, Certifications, and Warranty

This flag pole is rated for wind speeds up to 125 mph when unflagged. The fiberglass construction is non-conductive and corrosion-resistant.

LED Lighting Supply provides a 15 year warranty on this flag pole.
