World #1 Knot Site. Better to know a knot and not need it, than need a knot and not know it.
Tying the Strangle Knot (Using End) (Interactive Animation)
Use Arrow Keys
Strangle Knot (Using End)Pass the rope around the bar and then across the first turn. Pass the rope around a second time following the same path. Then tuck the rope under both of the first turns and pull tight. If the knot is laid incorrectly, the knot becomes a less secure half knot beside the two loops.
Strangle Knot (Using End) Details
Alternative techniques: In addition to using the end as shown in the animation, it can also be tied as a loop by forming a Double Overhand Knot and slid over a pole or sack.
Applications: A Strangle knot makes a reasonably secure temporary whipping and can be used to secure the neck of a bag or sack.
Disadvantages: The Strangle is less secure than the Constrictor Knot and cannot be tied by just twisting a loop. In addition, there is a significant risk of it being laid down wrongly so that it only forms a half knot beside two turns (see the final frame in the animation).
Release: Like the constrictor, the knot can be hard to undo - a knife may be necessary. If so, the binding strand should be cut over the other strands to protect the underlying rope.
Rope Size: The pictures here show the rope tied in large diameter rope. This is only for the photography. It is normally tied in twine or other small diameter line.
Disclaimer: Any activity that involves ropes is potentially hazardous. Lives may be at risk - possibly your own. Considerable attention and effort have been made to ensure that these descriptions are accurate. However, many critical factors cannot be controlled, including: the choice of materials; the age, size, and condition of ropes; and the accuracy with which these descriptions have been followed.
