Rope Bag, Chalk Bag,

rope bag
uThe rope bag is designed for storing and protecting climbing rope.
uThe bag, in addition to carrying the rope, also usually unfolds to provide a flat piece of material or tarp to place the rope on during climbs.
uThe tarp protects the rope from dirt and rock that might impair integrity by causing hard-to-see micro-cuts in the rope's sheath or internal core.
uWhen conditions are very wet, a large plastic bag, such as a garbage bag, may also be used.
chalk bag
uThese are hand-sized fabric bags for holding climbers' chalk.
uChalk bags are usually cylinder- or pouch-shaped and have openings that are controlled by drawstrings.
uThe inner fabric is usually fleece, which traps chalk powder.
uChalk bags are usually attached to the back of a waist belt for easy access by either hand during a climb.


Ascenders






uAscenders are mechanical devices for ascending on a rope. They are also called Jumars.
uJumars perform the same functionality as friction knots but are stronger, faster, safer and less effort is needed to use them.
uA Jumar employs a cam which allows the device to slide freely in one direction but tightly grip the rope when pulled on in the opposite direction.
uTo prevent a jumar from accidentally coming off the rope, a locking carabiner is used.

slings



uA sling or runner is an item of climbing equipment consisting of a tied or sewn loop of webbing that can be wrapped around sections of rock, hitched (tied) to other pieces of equipment or even tied directly to a tensioned line using a prusik knot, for anchor extension (to reduce rope drag and for other purposes), equalisation, or climbing the rope.

Figure 8




uAluminium (or occasionally steel) "8" shaped device.
uComes in several varieties
uUsed as a belay device
uFigure eights allow fast but controlled descent on a rope.

carabiner


-metal loop with spring-loaded gate (opening), used as

connector. Almost all carabiners for recreational climbing are

made from aluminium alloy. There are also steel carabiners.

-Types of carabiner: locking and non-locking.

-Types of gates including wire-gate, bent-gate, and straight-gate.
-Different gates have different strengths and uses. Most locking carabiners utilize a straight-gate.
-Bent-gate and wire-gate carabiners are usually found on the rope-end of quickdraws, as they facilitate easier rope clipping than straight-gate carabiners.


harness




uStrapping or equipment used to connect abseiling devices or ascending equipment to the body.
uA harness is also used for attaching the rope to a person.
