The figure-eight follow-through is the standard knot climbers use to tie the rope into their harness. It is strong, easy to inspect at a glance, and holds securely under load, which is why it is taught as the primary tie-in knot worldwide. Climbers finish it with a backup or stopper knot.
How to tie and check it
Tie a figure-eight in the rope, thread the tail through both tie-in points of your harness, then retrace it back through the original knot. Dress it flat and add a stopper knot. A correct knot shows five neat pairs of strands.
Why it’s the standard
Among the climbing knots, the figure-eight wins for tie-in because it’s hard to tie wrong and easy to verify — vital when your life hangs on it.
Partner check
Before climbing, climber and belayer check each other’s knot, harness, and belay setup. Make the figure-eight check part of every partner check, every time.
Frequently asked questions
Why do climbers use a figure-eight knot to tie in?
Because it is strong, secure under repeated loading, and — most importantly — easy to inspect. Its symmetrical shape means a partner can confirm at a glance that it's tied correctly, which is why it's the global standard for tying into a harness.
How do you tie a figure-eight follow-through?
Tie a single figure-eight in the rope about a metre from the end, thread the tail through both tie-in points of your harness, then retrace the original eight back through it. Dress the knot so the strands lie flat and finish with a stopper knot.
Do you need a backup knot with a figure eight?
A correctly tied and dressed figure-eight follow-through is secure on its own, but most climbers add a stopper (backup) knot in the tail. It uses up excess tail and gives an extra visual cue that the knot is complete.
