A figure-of-eight loop tied using the follow-through method. A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot.. In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabiners, such as when a group of people are climbing on the same top-rope.
The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Like the overhand knot , which will jam under strain, often requiring the rope to be cut, the figure-eight will also jam, but is usually more easily ...
Figure-eight knot of practical knot-tying, with ends joined. In knot theory, a figure-eight knot (also called Listing's knot [1]) is the unique knot with a crossing number of four. This makes it the knot with the third-smallest possible crossing number, after the unknot and the trefoil knot. The figure-eight knot is a prime knot.
The double bowline is one of the typical tie-in knots used in climbing, along with the figure eight follow through [3] [4] and the Yosemite bowline. [5] The advantage of the double bowline over the figure 8 is that it is easier to untie after being weighted in a fall, [3] [4] and so is used by sport climbers who take multiple lead falls and then have trouble untying their figure eights.
Stevedore knot (also known as Double figure eight): The Stevedore knot is tied at the end of a rope to prevent the end from unraveling, slipping through another knot, or passing back through a hole, block, or belay/rappel device. It is more bulky and less prone to jamming than the closely related figure-of-eight knot.
A double figure-eight loop, (also known as a bunny ears, or a dog eared loop) is a type of knot that forms two parallel loops, and resembles the figure-eight loop. [1]It is frequently used in climbing and caving as an easily untie-able knot that is capable of being attached to two bolts and equalised.
The figure-eight cannot be removed from the rope without detaching the device from the harness, and so could be accidentally dropped, particularly when tackling a rebelay. They also twist the rope which is a particular problem where a rebelay prevents the rope from untwisting.
The directional figure eight (a.k.a. inline figure-eight loop) is a loop knot. It is a knot that can be made on the bight. The loop must only be loaded in the correct direction or the knot may fail. It is useful on a hauling line to create loops that can be used as handholds.
