2. Anchor (climbing) - Wikipedia

   en.wikipedia.org/wiki/Anchor_(climbing)

   A living tree that is at least 15 centimetres (6 inches) in diameter will surely hold up several kilonewtons of force in any direction, and so is sufficient as being the sole anchor for any climbing anchor. A large (> 15 cm or 6 in diameter) and living tree is a natural anchor that is not redundant but still very strong.

3. Rock-climbing equipment - Wikipedia

   en.wikipedia.org/wiki/Rock-climbing_equipment

   Uses include creating friction prusik knots for ascending or gripping fixed climbing ropes, usually using thinner approximately 5 to 6 mm (0.20 to 0.24 in) cord, or for attaching to, and equalizing forces across, multiple fixed anchors points, [15] such as when setting up abseil or belay anchors on multi-pitch climbing routes, usually using ...

4. Snow anchor - Wikipedia

   en.wikipedia.org/wiki/Snow_anchor

   A snow anchor (also called a snow pro) is a type of natural or artificial protection used in mountaineering, alpine climbing and ice climbing as an anchor. Two common artificial devices are the snow fluke and snow picket. A snow anchor is used both for climbing and for securing tents and other camping gear, that is designed for use in sand and ...

5. Self-locking device - Wikipedia

   en.wikipedia.org/wiki/Self-locking_device

   The earliest type of self-belay device used was the ubiquitous prusik knotted sling used by climbers. The method requires the solo climber to feed out an estimated length of belay rope so that they can reach their next stance and repeat the process as the rope is difficult to feed through the prusik knot while climbing.

6. Climbing rope - Wikipedia

   en.wikipedia.org/wiki/Climbing_rope

   A climber and a belayer using a climbing rope. A climbing rope is a rope that is used in climbing.It is a critical part of an extensive chain of protective equipment (which also includes climbing harnesses, anchors, belay devices, and carabiners) used by climbers to help prevent potentially fatal fall-related accidents.

7. Bolt (climbing) - Wikipedia

   en.wikipedia.org/wiki/Bolt_(climbing)

   While bolts are commonplace in rock and gym climbing there is no universal vocabulary to describe them. Generally, a bolt hanger (or a fixed hanger) is a combination of a fixed bolt and a specialized stainless steel hanger designed to accept a carabiner, whereas in certain regions a bolt runner (or a carrot) describes a hangerless bolt (where the climber must provide their own hanger bracket ...

8. Grigri - Wikipedia

   en.wikipedia.org/wiki/Grigri

   While the Grigri was designed as a belay device, some big wall climbers (such as those climbing Yosemite's Half Dome or El Capitan) have invented novel ways to extend its use and compromise its safety. For example, some big wall rope soloists use the Grigri (sometimes slightly modified) as a self-feeding hands-free self-belay device.

9. Prusik - Wikipedia

   en.wikipedia.org/wiki/Prusik

   Escaping the Belay: In a lead-climbing situation, should the climber become incapacitated in a position where they cannot be safely lowered to the ground, the belayer must escape the belay in order to effect rescue. After locking the rope in the belay device with one hand, the belayer can tie a Prusik to the rope with the other hand, and then ...
