This 20-foot fiberglass flag pole is a strong choice for commercial and institutional sites needing a durable, low-maintenance flag display. Its engineered fiberglass construction resists corrosion and does not conduct electricity, making it well-suited for coastal, high-humidity, or electrically sensitive environments. The internal halyard system enhances tamper resistance and maintains a clean appearance, while the 125 mph wind rating (unflagged) supports reliable use in exposed locations. Direct burial installation with a ground sleeve ensures stability and a finished look. Ideal applications include schools, government buildings, corporate campuses, and sports facilities seeking long-term reliability with minimal upkeep.

Product Overview

This is a 20 foot fiberglass flag pole designed for in ground installation. The pole has a total height of 23 feet, with 20 feet above grade once installed. It is constructed from fiberglass and weighs 36 pounds.

The pole features an internal halyard system using a #10 (5/16 inch) rope. The finish is white, with custom color options available. The pole is supplied with a stationary truck, gold ball top, one set of brass snaps with white vinyl covers, a nylon cleat, and a 16 inch flash collar.

The ground level outside diameter is 5.75 inches, with a tip outside diameter of 3 inches. The included ground sleeve has an inside diameter of 8 inches and a length of 3 feet.

This flag pole is rated for wind speeds up to 125 mph when unflagged. The standard flag size for this pole is 4 x 6 feet.

Where This Product Fits Best

This fiberglass flag pole is suitable for both commercial and residential properties where a 20 foot above-grade flag display is required. It is often used at building entrances, parking lots, campuses, and public spaces.

The 125 mph wind rating supports use in areas with moderate to high wind exposure, provided the flag is removed during extreme conditions. The in ground installation method is appropriate for permanent applications where a stable, long-term flag display is needed.

The white finish and clean lines fit well with a range of architectural styles. Custom color options allow for site-specific visual requirements.

Performance and Functional Considerations

The fiberglass construction provides corrosion resistance and is non-conductive, which is useful in locations where metal poles are not preferred. The 36 pound weight allows for manageable handling during installation while maintaining structural integrity.

The internal halyard system reduces the risk of tampering and minimizes noise from rope movement. The stationary truck and gold ball top are standard for this pole type and support typical flag display requirements.

The 125 mph wind rating applies when the pole is unflagged. Actual wind tolerance will decrease when a flag is attached. The 4 x 6 foot standard flag size is matched to the pole's height and wind rating.

Installation and Long-Term Use

This flag pole is designed for in ground installation using the included 3 foot ground sleeve. The 8 inch inside diameter of the sleeve provides a stable base for the 5.75 inch ground level pole diameter.

The 16 inch flash collar covers the base and provides a finished appearance at grade. The pole's fiberglass material requires minimal maintenance and does not rust or corrode.

All necessary fittings for internal rope operation are included. The nylon cleat and brass snaps with vinyl covers are supplied for secure flag attachment and halyard management.

Long-term use is supported by the 15 year warranty provided by LED Lighting Supply.

How This Fixture Is Commonly Used

After installation, the internal halyard system allows you to raise and lower the flag without external ropes. This reduces noise and limits access to the halyard, which is useful in public or high-traffic areas.

The fiberglass pole can be cleaned with standard non-abrasive methods. The white finish maintains its appearance with periodic washing. The included flash collar helps keep debris and water away from the base.

Flag changes and halyard adjustments are performed at the base using the nylon cleat and brass snaps. The stationary truck and gold ball top remain fixed in place during normal operation.

The pole is designed for permanent, unattended flag display in environments where durability and low maintenance are priorities.

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. All included fittings and accessories are matched to the pole's specifications for safe operation.
