The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope.Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes.
An artificial climbing anchor consisting of a hex and two cams, equalized with slings. A snow picket . Depending on the surface being climbed, there are many types of protection that can be used to construct an anchor, including natural protection such as boulders and trees, or artificial protection such as cams , nuts , bolts or pitons .
1960s-era pitons, including: knifeblades, lost arrows, bugaboos, ring angles, and bongs. A piton (/ ˈ p iː t ɒ n /; also called pin or peg) in big wall climbing and in aid climbing is a metal spike (usually steel) that is driven into a crack or seam in the climbing surface using a climbing hammer, and which acts as an anchor for protecting the climber from falling or to assist progress in ...
Most commonly, a carabiner will be used to join the hex to the climbing rope by means of a loop of webbing, cord or a cable which is part of the hex. Hexes are a type of nut, a hollow eccentric hexagonal prism with tapered ends, usually threaded with webbing, a swaged cable, or a cord. They are manufactured by several firms, with a range of ...
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. Climbing ropes must meet very strict requirements so that they do not ...
An alternative V-shaped form of the death triangle involves clipping a single loop of webbing or cord to both anchors, then clipping the third carabiner over the loop rather than through it, allowing the latter to slip off the loop if either anchor fails. Two better methods are (a) putting a half twist in the cord and clipping the free ...
In climbing, a Tyrolean traverse is a technique that enables climbers to cross a void between two fixed points, such as between a headland and a detached rock pillar (e.g. a sea stack), or between two points that enable the climbers to cross over an obstacle such as chasm or ravine, or over a fast moving river.

Sit harness. A climbing harness is a piece of equipment that allows a climber to tie in to the safety of a rope. [1] It is used in rock and ice climbing, abseiling, and lowering; this is in contrast to other activities requiring ropes for access or safety such as industrial rope work (such as window cleaning), construction, and rescue and recovery, which use safety harnesses instead.
