What kind of knot is commonly used to secure a harness?

The figure-eight follow-through knot is often used to secure a harness due to its strength and reliability. This knot provides a secure method for anchoring the harness to the rope, ensuring that it does not slip under load. When tying this knot, the rope forms a distinctive figure-eight shape and then passes back through the loop created, which helps to maintain the knot's integrity when subjected to tension.

This knot is favored in climbing and rescue operations because it is easy to inspect visually, confirming that it is tied correctly. It also allows for easy adjustment and is less likely to come undone than some simpler knots, making it an ideal choice for scenarios where safety is paramount.
