Internal Winch Flagpoles
Price range: $3,508.00 through $31,076.00
The Internal Winch Series is FlagCo’s standard commercial flagpole for schools, government facilities, and corporate campuses that need reliable flag display without exposed hardware. An internal hand-crank winch raises and lowers the flag entirely from inside a ground-level access door, keeping the exterior shaft clean and eliminating vandalism exposure on the halyard system. Available in 20 ft through 80 ft heights, with published wind ratings per NAAMM FP 1001-07 for every configuration.
Why the Internal Winch Series?
The premium internal halyard solution for commercial properties that need security, a clean appearance, and the strength to handle heights up to 80 feet.
Tamper-Resistant by Design
The entire halyard is concealed inside the pole, accessible only through a keyed flush-mount access door at the base. The stainless steel winch with removable hand crank means your flag cannot be lowered without authorization, ideal for schools, government buildings, and high-visibility commercial sites.
Sleek, Professional Appearance
No visible rope, no external hardware, no cleat on the shaft. The clean exterior makes the Internal Winch Series the preferred choice for architectural and high-profile commercial applications where aesthetics matter as much as function. The pole looks exactly as it should, like a flagpole, nothing else.
Engineered for Reliability
The internal halyard assembly includes a plastic-coated counterweight, beaded retainer ring, and stainless steel swivel flagsnaps, components engineered to cycle smoothly for years without corrosion. Flags 8'×12' and larger include a heavy-duty shock spring assembly to protect against snap loads in high wind.
Available to 80 Feet
The Internal Winch Series covers the full commercial height range, 20' through 80', making it the most capable internal halyard option we offer. Heights above 40' include heavy-duty upgrades for 10" diameter configurations: sealed bearing truck, heavy-duty stainless flagsnaps, and cast aluminum flash collar.

Frequently Asked Questions
What's the difference between external and internal halyard?
What wind speed can these flagpoles withstand?
Do I need a foundation? What's included?
How long does shipping take?
Most flagpoles ship within 5-7 business days. Multi-section poles (35’+) ship via freight carrier and require a delivery appointment. Free shipping on all orders over $500.
What size flag should I fly?
Each configuration has a recommended flag size, which you can see in the configuration table above. As a rule of thumb: 20′ poles fly a 4’×6′, 25’–35′ poles fly a 5’×8′ or 6’×10′, 40’–45′ poles fly an 8’×12′, 50’–60′ fly a 10’×15′ or 12’×18′, and the 80′ flies a 15’×25′. We sell all standard flag sizes.
What's the difference between 1-section and 2-section poles?
A 1-section pole is a single continuous shaft, stronger and cleaner looking, but harder to ship and install for taller sizes. A 2-section pole ships in two pieces that sleeve together on-site. Wind ratings are the same for both. The 2-section option costs slightly more due to the additional machining but makes delivery and installation easier, especially for heights over 30′.
