How to Replace a Broken Flagpole Rope

How to Fix or Replace Damaged Flagpole Rope

A broken halyard (flagpole rope) doesn’t mean the end of your American flag display — but it does require careful replacement to restore safe, respectful operation.

Whether your rope has snapped due to weather, wear, or time, this step-by-step guide will walk you through how to replace it properly without damaging the pole or hardware.

1. Determine Your Flagpole Type

Before starting, confirm whether your flagpole is:

  • External halyard: Rope runs along the outside of the pole with a cleat at the bottom.

  • Internal halyard: Rope or cable runs inside the pole, often with a locking door.

  • Telescoping pole: No traditional rope; sections collapse and extend with spring buttons.

This guide applies to external halyard flagpoles, which are the most common residential style.

2. Lower the Flag and Remove Old Rope

If your rope is broken but still partially attached:

  • Lower the flag if possible.

  • Untie or unclip it from the remaining rope.

  • Carefully pull out all the old rope from the pulley at the top (called the "truck").

If the rope has snapped completely and is no longer accessible:

  • You may need to rent or borrow a lift, or contact a local installer for high pole service.

For most residential 20–25 ft poles, a fiberglass extension ladder and safety harness can work if you're experienced and careful.

3. Choose the Right Replacement Rope

Use solid braided polyester halyard rope, which is UV- and weather-resistant.

Typical sizing:

  • 5/16" thickness for most 20–25 ft poles

  • Length = Twice the height of your pole plus 10% extra

4. Thread the New Rope Through the Pulley

Use a temporary guide rope to help thread the new halyard:

  • Tie the new rope end to the old one (or to a small weighted string)

  • Slowly pull it over the pulley until the new rope comes out the other side

  • Center the rope so both ends hang evenly

Tip: Wrap tape around the knot to reduce snags while pulling.

5. Secure Hardware and Reattach Flag

Once threaded:

  • Tie a secure knot (like a bowline) on each end

  • Attach snap hooks with crimps or knots to hold the flag

  • Test the up/down movement to ensure it slides smoothly

  • Tie off excess rope to the cleat
