How to Tie a Double Fisherman's Knot for Climbing

Need to know how to tie a double fisherman’s knot?  A double fisherman’s knot is a way of joining two separate pieces of rope together. It has an extra loop and is more heavy duty than a single fisherman’s knot.

1. Take the ends of 2 pieces of rope so they are parallel to each other. Taking the end of a rope, wrap it around the other rope from front to back.
2. In addition to going behind, or under, the other rope in Step 1, make sure that the rope is also under, or behind, itself. Once the end comes around to the front, this wrap around has made a complete circle. 
3. Repeat by wrapping the rope a second time, making sure the second wrap is below the first one.
4. Take the working end of the rope and thread it under, or behind, both wraps.
5. Pull to tighten.  This completes the first part of the double fisherman's knot.

The same steps have to be done again using the second rope, only they will be in the opposite direction:

1. Take the other end of the second rope, the one that hasn’t been knotted yet, and wrap it around the first rope from back to front.
2. In addition to coming over the front of the other rope, make sure that it is also in front, or on top of, itself.  Once that is done, the wrap around has made a complete circle.
3. Repeat by wrapping the rope a second time, making sure the second wrap is above the first one.
4. Take the working end of the rope and thread it through both wraps.
5. Pull on both ropes so that both knots lie snug against each other.
6. Pull to tighten. This completes the double fisherman's knot.  

Caution: Make sure the knots fit tightly together.  If they don’t, the double fisherman's knot may be tied incorrectly. Allow enough rope to work with so there will be a sufficient tail after the knot is completed to avoid coming untied.
