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 ...

   Blake's hitch: Blake's hitch is widely used in tree climbing applications. The knot can be slid up and down a line manually, but when loaded, it sticks securely. Girth hitch: This hitch is commonly used to attach loops of runner to harnesses, bags, other kinds of equipment, and to natural features like rock knobs or brush/tree trunks for ...

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. Belaying - Wikipedia

   en.wikipedia.org/wiki/Belaying

   To set up this anchor the belayer should place a piece of directional protection (i.e., a nut or cam) into a crack below their body, or tie themselves by the belay loop to a rock or tree. The anchor arrests any upward force produced during a fall thus preventing the belayer from "taking off".

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. 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 ...

9. 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.
