Product Overview
This 20-foot fiberglass flag pole is designed for permanent in-ground installation with a total height of 23 feet, placing 20 feet above grade after burial. The pole features a round tapered profile with a 5.75-inch outside diameter at ground level, narrowing to 3 inches at the tip. Total weight is 36 pounds.
The internal halyard system routes the flag line inside the pole shaft, using #10 (5/16-inch) halyard. Standard configuration includes a stationary truck, 6-inch gold ball top, brass snaps with white vinyl covers, nylon cleat, and 16-inch flash collar. The pole ships in white finish with custom color options available.
Where This Product Fits Best
This pole is rated for 125 mph wind speeds in unflagged condition. Fiberglass construction provides corrosion resistance in coastal, humid, or chemically exposed environments where steel or aluminum poles may degrade over time. The 20-foot above-grade height accommodates a standard 4 x 6 foot flag.
In-ground installation with the included 3-foot ground sleeve positions this pole for permanent civic, commercial, or institutional applications. The internal halyard design reduces external hardware and protects the flag line from weather exposure and tampering.
Performance and Functional Considerations
The 125 mph wind rating applies to the pole in unflagged condition. When a flag is flown, wind load increases and effective wind tolerance decreases. Flag size selection should account for local wind conditions and expected sustained or gust speeds at the installation site.
Fiberglass does not conduct electricity, which can be a consideration for installations near electrical infrastructure or in lightning-prone areas. The material resists rust, rot, and salt corrosion without requiring protective coatings or regular refinishing.
Installation and Long-Term Use
The pole installs into a ground sleeve with an 8-inch inside diameter and 3-foot length. Site preparation requires excavation to accommodate the sleeve plus appropriate base material for drainage and stability. The flash collar covers the junction between pole and ground surface.
At 36 pounds, the pole can typically be raised and positioned by a small crew without mechanical lifting equipment. The internal halyard runs through the pole interior and is accessed via the cleat mounted on the pole exterior.
How This Fixture Is Commonly Used
Flag changes are made using the internal halyard system. The nylon cleat secures the halyard at the desired flag height. Brass snaps with vinyl covers attach the flag grommets to the halyard line. The stationary truck at the pole tip holds the halyard pulley in fixed position.
Routine maintenance involves inspecting the halyard for wear, checking snap hardware, and verifying cleat security. The fiberglass shaft does not require painting or coating maintenance under normal conditions. The white finish can be cleaned with standard exterior cleaning methods.
Safety, Certifications, and Warranty
This flag pole carries a 15-year warranty. The 125 mph wind rating reflects structural performance in unflagged condition under rated wind loads.
Installation should follow local building codes and permit requirements. Foundation preparation and concrete specifications depend on soil conditions and local engineering standards.
