Vertical caving terminology and methods > Knots > Common knots
A knot tied on a bight. Made from a figure of 8 on a bight with an extra half turn. Used to create a loop that can be clipped into a carabiner. An alternative to the figure of 8 on a bight when extra strength is desired, though in reality, a figure of 8 on a bight is already more than strong enough in all places where it would be used. Less resistant to cross loading than a figure of 8 on a bight, and severe cross loading causes the knot to deform or possibly capsize, and lose some of its strength.
