Quad Anchor – How to Make a Quad Anchor

Quad Anchor

The quad anchor is a versatile method to equalize any anchor.

First, I’ll explain how to apply one on a 2-bolt anchor for a top rope.

Then, you can watch Angela demonstrate a number of different ways to tie one in the Building Quad Anchors for Rock Climbing video below.

The advantages to using a quad anchor are many:

  • It’s redundant.
  • It self-equalizes
  • It’s quick to tie
  • It’s easy to double check.

Gear You Need:

  • 1 Cordelette (6mm Sterling Power Cord or 7mm nylon cord, at least 15 foot in length). Join the two ends with a double fisherman’s or another knot of your choice.
  • 4 locking carabiners. I recommend 2 smaller locking carabiners like the Petzl Spirit and 2 larger, pear-shaped locking carabiners like the Petzl Attache.

4 Steps to Building a Quad Anchor:

  1. Double your cordelette over so you have 4 even strands. Position the knot that joins the two ends to one end of your loops.

Keep them a little loose so you can slide them closer together or further apart depending on how much lateral movement you need.

3. Clip your SMALL locking carabiners to the loops on either end of the cordelette. You will clip this to each of the two bolts.

4. Separate the 4 center strands, and clip your 1 LARGE locking carabiners to two out of the four strands in the middle, then clip your last locking carabiner to the remaining two center strands. For best practice, make sure you opposite and oppose them.
