How to Tie the Double Dragon Loop (Mid-Line)
Usage
The Double Dragon Loop (Mid-Line) is a super secure, non-jamming inline loop that’s a solid alternative to the Alpine Butterfly Loop or Span Loop, especially when you need a more directional, load-balanced knot. Unlike some mid-line loops, this one holds tight under tension and won’t jam up, making it a go-to for climbing, rigging, and rescue work.
Why Learn the Double Dragon Loop (Mid-Line)?
- Highly secure and stable, even under dynamic loads.
- Non-jamming, making it easy to untie after heavy loading.
- Excellent inline loop for directional load applications.
- Works well with modern synthetic ropes, reducing slip concerns.
Common Uses
- Climbing & Rescue: Creating stable attachment points in the middle of a rope.
- Boating & Marine: Forming secure inline loops for load distribution.
- General Utility: Used for setting up tensioned lines and rigging.

Notable Features
- Exceptionally Secure: Holds firm under load without slipping.
- Non-Jamming: Easily untied even after significant tension.
- Directional Load Bearing: Great for tensioned applications.
- Can Be Tied Mid-Line: You don't need the end to tie it.
Variations
- Double Dragon Loop (Rope End) vs. The Double Dragon Loop (Mid-Line):
- Double Dragon Loop (Rope End): Tied at the end of a rope for anchoring.
- Double Dragon Loop (Mid-Line): Forms a strong, load-bearing loop in the middle of a rope.
Similar Knots
Butterfly Knot vs. Double Dragon Loop (Mid-Line)
- Pros: Stable and distributes load well in multiple directions.
- Cons: More complex to tie than the Double Dragon Loop (Mid-Line).
Span Loop vs. Double Dragon Loop (Mid-Line)
- Pros: Strong inline loop that distributes force evenly.
- Cons: Can be harder to tie and adjust under load.
Perfection Loop vs. Double Dragon Loop (Mid-Line)
- Pros: Compact and simple loop for fixed end applications.
- Cons: Less suitable for mid-line uses where directional load is needed.
History
The Double Dragon Loop (Mid-Line) is a modern adaptation of the Double Dragon Knot, optimized for mid-line applications. Unlike traditional mid-line loops like the Alpine Butterfly, it provides a more directional load-bearing capacity, making it particularly useful for tensioned lines. It does not appear in The Ashley Book of Knots, but has been widely adopted in climbing, rigging, and marine use for its secure and non-jamming properties.

Security Level
The Double Dragon Loop (Mid-Line) is highly secure, resisting shaking and loosening even under dynamic loads. It maintains its integrity across various rope materials and is one of the best options for inline load-bearing knots.
Downsides
- Less Commonly Known: Users must ensure proper tying technique.
- Bulkier than the Alpine Butterfly: May not be ideal for compact setups.
Structure (Step-by-Step Instructions)
- Create a bight in the rope where the loop will be formed.
- Wrap the working end around the standing part twice, forming a double coil.
- Thread the working end back through both coils from underneath.
- Tighten the knot by pulling on both standing parts while shaping the loop.
- Ensure the knot is properly dressed and secured before applying load.
FAQ
How does the Double Dragon Loop (Mid-Line) compare to the Alpine Butterfly Loop?
It is more directional and secure under dynamic loads, but bulkier.

Yes, it is an excellent choice for creating inline attachment points in climbing setups.
What makes the Double Dragon Loop (Mid-Line) better than the Span Loop?
It is easier to tie and provides a secure load-bearing loop with minimal slip risk.
Is the Double Dragon Loop (Mid-Line) difficult to untie?
No, it remains non-jamming and can be loosened after load application.
Important Notes on Safety
- Ensure proper tying technique to maintain security.
- Check for proper loop orientation when using for directional loads.
- Inspect the knot before applying significant weight.
