How to Tie the Double Figure Eight Loop Knot
The Double Figure Eight Loop
The Double Figure Eight Loop is a secure fixed-loop knot used to create two load-sharing loops at the end of a rope. It is commonly used in climbing, rescue work, rigging, and other rope applications where multiple attachment points or improved load distribution are desirable. Valued for its strength, stability, and ease of inspection, the knot provides a reliable means of attaching a rope to anchors, hardware, or other components of a rope system.

Double Figure Eight Loop Instructions
The Double Figure Eight Loop is listed in The Ashley Book of Knots (ABOK #1085) and is recognized as a variation of the Figure Eight family that forms two loops from a single knot structure. Its design distributes load across multiple strands while maintaining the security and recognizable appearance associated with figure-eight-based knots. The loop knot can be adjusted to create equal or unequal loop sizes depending on the intended application, making it versatile for a variety of rigging and anchoring situations.
For other double loop knots, see the Double Alpine Butterfly Loop or Bowline on a Bight. Despite the alternatives, the Double Figure Eight Loop is decisively the securest double loop knot.
Key Considerations
Proper dressing of the Double Figure Eight Loop is important to ensure the strands lie neatly and the loops are correctly formed. A well-dressed knot helps distribute load evenly and allows the structure to be inspected quickly for errors. As with all critical rope knots, it should be checked after tying to verify that the loops are properly sized, the strands are aligned, and sufficient tail length remains.
Advantages & Disadvantages
One of the key advantages of the Double Figure Eight Loop is its ability to provide two secure attachment points while retaining the strength and reliability of the figure-eight structure. It performs well under load, is relatively easy to inspect, and remains stable in a wide range of rope materials and conditions. Although it may be bulkier than some alternative double-loop knots, its security and predictable behavior have made it a respected choice in climbing, rescue, and technical rope work.
ABOK #1085 - Double Figure Eight Loop
ABOK Numbers: Abok #1085
The Double Figure Eight loop is featured in Ashley’s Book of Knots as a single entry. Clifford doesn’t go into much detail about the pros and cons, focusing more on how to tie the knot. The exact entry is as follows:
Abok #1085,
‘A rigid Double Figure-Eight Loop. The loops are narrow and parallel. Double your rope and tie the looped end in the form figure eight but without making a final tuck. It should coincide with the left diagram. The loop that was formed should be laid back underneath against the doubled standing part which is to form the neck of the knot. See the right diagram. Two bights from the neck of the single loop are then grasped (third diagram) and pulled down through the double loop. Draw up evenly to form the knot pictured in the center.’
