A cordelette is a long loop of accessory cord — typically 5 to 7 metres of 6-7mm cord tied with a double fisherman’s knot — used to link the points of a climbing anchor and equalize them to a single master point. It is a simple, versatile, and inexpensive way to build a solid multi-point anchor.
How it’s used
Clip it to the anchor points, pull the strands down between them, and tie off so the load shares to one master point — a practical way to achieve equalization.
Make-up
Joined into a loop with a double fisherman’s knot.
Good to know
A staple for building trad and multi-pitch anchors.
Frequently asked questions
What is a cordelette used for?
It's used to build anchors: you clip the loop to two or three anchor points, pull the strands down between them, and tie them off so the load is shared and brought to one master point. It's one of the most common and reliable ways to rig a multi-point belay anchor.
How long is a cordelette?
Typically a loop made from about 5 to 7 metres of 6 or 7 mm nylon or high-strength cord, joined into a loop with a double fisherman's knot. The length lets it reach and equalize spread-out anchor points.
Cordelette or sling for anchors?
Both work. A cordelette is longer and excels at equalizing three points to a tidy master point, while a long sling is lighter and quicker for two-point anchors. Many climbers carry both and choose based on the anchor.
