+ How to Tie a Figure-8 Follow-Through β€” Step-by-Step Climbing Knot Guide | BoulderingList

Figure-8 Follow-Through

beginner

The figure-8 follow-through is the climbing tie-in knot used by virtually every climbing gym and instructor in the world. Tied through both tie-in points of the harness.

When to Use

The standard climbing tie-in knot used to attach the rope to a climber's harness.

The figure-8 follow-through (sometimes "rewoven figure-8" or "trace-eight") is the standard climbing tie-in knot. The climber ties a figure-8 knot in the rope, threads the working end through both tie-in points of their harness, and then "follows the rope back through" the original figure-8, mirroring its path. The result is a strong, easily-inspected knot that ties the climber to the rope.

Why this knot? Two reasons. First, it is easy to inspect at a glance β€” both legs of the rope follow the same figure-8 path, so any partner can verify the knot is correctly tied in two seconds. Second, it tightens under load and stays put. The figure-8 follow-through has caught millions of climbing falls without slipping.

The knot is taught in every belay course at every climbing gym worldwide. Always tie in through both the waistbelt and leg-loop tie-in points (never the belay loop). Always finish with a stopper knot β€” most gyms require this. And always do a partner check before climbing: harness, knot, belay device, locked carabiner.

How to Tie the Figure-8 Follow-Through

  1. Step 1

    Tie a loose figure-8 knot in the rope, leaving roughly 1 metre of working end past the knot.

  2. Step 2

    Thread the working end through both tie-in points on your harness β€” the lower one first (above the leg loop attachment), then the upper one (under the waistbelt).

  3. Step 3

    Follow the rope back through the figure-8, tracing its exact path in reverse. The working end should mirror every twist and turn of the original figure-8.

  4. Step 4

    Pull both ends to dress the knot. Both legs of the rope should sit parallel through every turn of the figure-8, with no twists.

  5. Step 5

    Tie a stopper knot (overhand or double overhand) on the working end against the main figure-8. Leave at least 5 cm of tail past the stopper.

  6. Step 6

    Do a partner check: harness buckled correctly, knot threaded through both tie-in points, knot dressed cleanly, stopper knot present, belayer's device set correctly with locked carabiner.

Tips for Tying It Well

  • The trace step is the critical part. Take your time β€” the working end should mirror the original figure-8's every turn.
  • Always tie in through BOTH the waistbelt and leg-loop tie-in points β€” never just the belay loop.
  • Leave a generous tail (10-15 cm) past the stopper knot. Short tails can pull through under load.
  • Get into the habit of partner-checking every climber before they leave the ground. Make it ritual.

Common Mistakes

  • Tying in through the belay loop only. The belay loop is for the belay device β€” never for the rope. Always thread through the harness tie-in points.
  • Forgetting the stopper knot. Most gyms will not let you climb without one.
  • Crossing the rope strands inside the figure-8 (not following the path cleanly). Cross-strands weaken the knot and make it harder to untie later.
  • Skipping the partner check. Even experienced climbers occasionally tie in incorrectly. The check takes 5 seconds and has saved lives.
