What size is a Cordelette?
Cordelette: Use 18 to 20 feet of 7mm or 8mm nylon cord or 5mm high-strength UHMW polyethylene (such as Spectra or Dyneema) tied in a loop. Use a double fisherman’s knot for Perlon cord or a triple fisherman’s knot for the thinner UHMW polyethylene cord.
What’s a Cordelette?
The cordelette is just a large sling, 6 or so metres in length. To create one on the cheap it can be made from 7mm or thicker accessory cord (perlon) tied in a loop with a triple fisherman’s knot (as for double fishermans, but with an extra stopper knot on each side).
How strong is Cordelette?
No anchor-building material is perfect, all of them having tradeoffs between strength, weight, bulk, durability, dynamic properties and versatility. Mammut’s 5 mm accessory cord has a breaking strength of 5.5kn (about 1200lb), 6mm is 7.5kn (about 1700lb) and 7mm 13kn (about 2900lb).
How much cord do I need for a Prusik loop?
To make a prusik loop: Measure: Multiply the finished loop by two and add 1 foot for knots. Thus an 18″ prusik loop will require 4′ of rope. Tape: Wrap the accessory cord with masking tape.
Is webbing stronger than rope?
Abrasion Resistance Tests show static rope is about three times stronger than webbing when pulled down over an edge, and vastly superior when pulled along a sharp edge, as would happen if the master point shifted during a traversing climb.
How long should climbing Cordelette be?
To make a cordelette, take an 18–20 ft. long section of seven- to eight-millimeter Perlon accessory cord and use a double fisherman’s knot to tie the cord into one big loop.
What is Cordelette made of?
A cordelette can be made of 6mm or 7mm nylon cord or 5.5mm Dyneema cord. I prefer to use 20 feet of 7mm cord for its strength, versatility, and resistance to fatigue. The cord can be permanently tied into a loop using double fisherman knots for nylon cord or triple fisherman for the Dyneema materials.

What are the benefits of using a cordelette?
As well as fast equalisation, another major benefit of using a cordelette, knotted as shown, is that it effectively ties off each anchor, offering very little extension if one of the anchors fails. Obviously the system relies on the direction of the load being known beforehand.
