Cord that typically ranges in diameter from 2 to 8 millimeters and is typically fabricated from Kevlar, nylon, Dyneema, Spectra, Perlon, and/or polyester fibers.
Gear which actively expands to fit cracks, pockets, etc.; cams are active protection because they place an active outward pressure on the rock.
A style of rock climbing which involves the pulling and standing on pieces of gear to assist in ascending a route.
Ladders made of webbing used by aid climbers to step up.
The brand name of a type of spring-loaded camming device (SLCD).
An anchor setup in which a piece of webbing or cord is threaded through two anchor points and then the ends tied together. This creates a triangle that increases the force on each anchor. This is dangerous when the anchors are not bomber and this setup is not redundant if only one piece of webbing or cord is used.

Multifunctional metal piece of hardware used for belaying, rappelling, attaching to an anchor, and much more.
Technically called a spring-loaded camming device, cams are a type of protection placed into cracks. Usually comprised of either three or four lobes and one or two axles, cams convert the pulling force of a falling climber into an outward pressure on the rock.

All ropes used for climbing are dynamic ropes, meaning they slightly stretch when a climber falls. This stretching provides a softer catch for the climber and places less force on the anchors.
A dynamic climbing move in which the climber leaps for a hold, completely releasing him or her from the rock face.
A type of climbing hold; a very small ledge.
To place the outside or inside edge of the climbing shoe on a thin foothold.
The equal distribution of force across all protection in an anchor.
A method used to ensure proper anchor configuration; the acronym stands for equalized, redundant, non-extending, strong, timely.
European Death Knot (EDK)
This is simply another name for the offset overhand bend. The knot gained it’s name out of fear that it would roll and fail while rappelling, but if given a sufficient tail this is a very unlikely.
1) The elongation of anchor slings or webbing due to a failed piece of protection. An important consideration while anchor building is ensuring that the anchor doesn’t extend should any single component fail. Extension can be prevented by implementing a load-limiting knot. 2) To use extender slings on protection, thus reducing rope drag.
A measurement of a fall’s intensity; calculated by dividing the length of the fall by the amount of rope in the system (measurement of rope from the belay device to the climber).

To counter-press two widely spaced footholds.
To use a stick (or long rod) to pre-clip the first bolt on a route, thus preventing a ground fall should the climber fall before the first bolt.
A knot tied at the end of the rope when rappelling so that the climber cannot rappel off the end of the rope; should also be tied into the end of the rope opposite the climber when top roping to prevent the end of the rope sliding through the belay device if the rope is not long enough.
Accronym for tri-cam unit, a spring-loaded camming device with three cam lobes instead of four; typically for very thin cracks.
A style of climbing where the rope runs from the climber, up through the anchors, and then down to the belayer. This setup is called a “slingshot” top rope and it enables the belayer to immediately catch the climber upon falling (as opposed to the large fall potential of lead climbing).
Short for traditional, this is a style of climbing in which the climber places small pieces of gear (usually cams and nuts) to protect him or herself in the case of a fall. This is a very clean style of climbing due to its minimal impact on the rock.
