Caring for and Coiling the Climbing Rope

• a. Keep the rope clean.
• b. Always coil a rope before storing it.
• c. Make sure wet rope is dry before coiling it.
• d. Return rope to its proper place after using it.

Bowline on a coil

Bowline on a coil

Use: This is used as an impromptu harness, however is not recommended today since there are commercially available pre-fabricated harnesses. This method is preferable to a single loop because it distributes weight across all the loops/wraps. How to tie: To tie, wrap about 15 feet from the loose end of the rope around your body. Form a loop from the (non-loose) end of the rope (like a regular bowline) and slip it under the rope around your body. Thread the loose end of the rope through the loop, around the long end, and back through the loop (like a regular bowline).

Bowline on a bight

Bowline on a bight

Use: This makes a secure loop in the middle of a rope which does not slip. How to tie: A bight is the middle part of the rope (not the ends) In the middle of a rope, form a small loop. Thread the bight through the loop. Spread out the bight a little. Pass this down and around the whole knot. Continue until it come back to the neck where it started. Tighten the bight to complete the knot. Tighten carefully so that you don't get a kind of slip knot.

Figure Eight

Figure Eight
Use: This knot is ideal for keeping the end of a rope from running out of tackle or pulley. How to tie: Make underhand loop, bringing end around and over the standing part. Pass end under, then up through the loop. Draw up tight.

Ring Bend

Ring Bend (Water Knot, Tape Knot)

Use: The water knot (or tape knot) is a knot frequently used in climbing for joining two ends of webbing together, for instance when making a sling. The ends should be left at least three inches long and the knot should be "set" by tightening it with full body weight. The ends can be taped or lightly sewn to the standing parts to help prevent them from creeping back into the knot. Inspect the knot before each use. How to tie: To tie, first form an overhand knot in one end and then follow it with the other end, feeding in the opposite direction.

Double Fisherman's

Double Fisherman's Knot

Use: Joining thin, stiff or slippery lines, backing up critical knots such as the Figure-of-eight loop or Figure-of-eight follow through. Use the double fisherman's knot to tie together two ropes of unequal sizes. This knot and the triple fisherman's knot are the variations used most often in rock climbing, but other uses include search and rescue. The primary use of this knot in rock climbing is to form high strength loops of cord for connecting pieces of the rock climber's protection system. It is favoured for being compact, and for arranging the line of force in a straight line through the knot. Another common use for this knot is to back up a critical knot, such as a harness tie-in knot or single-line rappel rigs. In this use, the running end is tied around the standing end of the rope, so that it cannot slip back through the knot. How to tie: See illustration. Draw up tight.

Prusik

Prusik knot

Use: A Prusik (aka Prussik or Prussic) is a friction hitch used in climbing, canyoneering, caving, rope rescue and by arborists to grab a rope (sometimes referred to as a rope-grab). The term Prusik is used both for the knot, for the loops of cord, and for the action (to prusik). A Prusik rope is a circular loop with a circumference of 20 to 100 cm depending on its intended use. Two Prusik ropes are tied to another rope which is anchored above. When the Prusik knot is under tension, it grabs the rope to which it is tied. When not under tension, it is easily moved. The climber places one foot into each loop, and shifts all of his or her weight to one of them, releasing the tension on the other. The rope without tension is then slid upwards on the vertical rope. The climber then shifts his or her weight to the other loop and slides the first one up. This is repeated until the rope has been ascended. Prusiks will work around two ropes, even two ropes of different diameters. Prusiks provide a high-strength and relatively fail-safe (i.e., they will slip before damaging the rope or breaking) attachment, and are used in some rope-rescue techniques. Prusiks are good to use in hauling systems where multiple rope-grabs may be needed, and where mechanical rope-grabs are not available. Although the Prusik Climb technique may be called old-school by some, the US Army still includes it in its annual Best Ranger competition. Rangers in the competition routinely make it up a 90 foot rope in under a minute. How to tie: The Prusik is tied by wrapping the prusik loop around the rope a number of times (depending on the materials, but usually 3-5 times), and then back through itself, forming a barrel around the rope, with a tail hanging out the middle. When the tail is weighted the turns tighten around the main rope and grab. When weight is removed the loop can be slid along the rope by placing a hand directly on the barrel and pushing. The trick is, if it grabs well, then it is hard to slide along the rope. Breaking the Prusik free from the rope after it has been weighted can be difficult, and is easiest done by pushing the bow, being the loop of cord which runs from the top wrap, over the knot to the bottom wrap, along the tail a little. This loosens the grip of the hitch and makes movement easier. Step 1 Step 2 Step 3 Step 4 Locked while holding tension. Slides readily without tension.

10

Show how to set up a rappel. Rappel using figure eights or other mechanical brake methods. Do at least two 50-foot (15.24 meters) rappels.

Figure eight

Sometimes just called "eight", this device is most commonly used as a descender, but may also be used as a belay device in the absence of more appropriate equipment.

It is an aluminium (or occasionally steel) "8" shaped device, but comes in several varieties. Its main advantage is efficient heat dissipation. A square eight, used in rescue applications, is better for rappelling than the traditional 8. Because of the "ears" or "wings" on the rescue 8, there is less chance of forming a girth hitch while rappelling very quickly.

A figure eight descender

Figure eights allow fast but controlled descent on a rope. They are easy to set up and are effective in dissipating the heat caused by friction but have a tendency to put a twist in the rope. This twisting only occurs during improper use of the 8. Holding the brake hand off to the side twists the rope, whereas holding the brake hand straight down, parallel to the body, allows a controlled descent without twisting the rope. Because of the many bends it puts into the rope, an 8 descender can wear a rope quicker than a tube style belay/rappel device. Many sport climbers also avoid them because of the extra bulk an 8 puts on the rack. However, many ice climbers prefer to use the 8, because it is much easier to thread with stiff or frozen rope.

Rescue eight

A rescue eight is a variation of a figure eight, with "ears" or "wings" which prevent the rope from "locking up" or creating a girth hitch, thus stranding the rappeller on the rope. Rescue eights are frequently made of steel, rather than aluminum.
