This device utilizes a large surface area in contact with a climbing rope to provide sufficient friction along with the proper technique to be used as a belay device or for rappelling. A figure 8 (sometimes just referred to as an 8) is used in conjunction with a climbing harness and locking carabiner to control a belayed climber's descent, or ...
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.
Abseiling (/ ˈ æ b s eɪ l / AB-sayl or / ˈ ɑː p z aɪ l / AHP-zyle; from German abseilen 'to rope down'), also known as rappelling (/ ˈ r æ p ɛ l / RAP-pell or / r ə ˈ p ɛ l / rə-PELL; from French rappeler 'to recall, to pull through'), is the controlled descent of a steep slope, such as a rock face, by moving down a rope.
It is designed to help stop rope twisting. Figure eights, although not the most common belay device, are still frequently found in use. For most uses, a tubular style belay device is easier and safer to use. However, due to their tendency to twist rope [3] and general disagreement about their safety, figure eights are often banned in climbing gyms.
As mentioned earlier, this knot can replace the figure-eight knot when tying into a climbing harness by tying a regular bowline knot and then re-threading it, such as is done with a figure eight knot. However, it is critical to use a strong backup knot with plenty of tail beyond the knot, as the knot may untie during long climbs. The advantage ...
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 ...
When finished, the working end forms a figure eight. Because of the danger of incorrectly dressing the Yosemite bowline and capsizing it even before it is set, it may be safer and less error-prone to use a standard or double bowline with a backup stopper knot added to the tail, such as a double overhand knot tied around the loop.
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.
