a minimum of 12 falls and in accordance with UIAA standards. Not to
be smaller than 10.5mm in diameter.
Daisy Chain A runner that has numerous loops through its entire
length, in which carabiners and climbing hardware can be clipped.
Dynamic Rope Ropes that stretch more than 10% or more of their
length with a load of approximately 1 KN.
Fall Line The vertical path followed by a hanging rope.
Figure 8 1. Rappelling device that is shaped like an eight.
2. A very useful knot that looks like an eight, used by climbers for
tying to the end of the rope.
Harness - A professionally constructed piece of software to attach
a climber and belayer to the rope.
Haul Line the part of a rope in a hauling system pulled by hand
or mechanical ascender to raise a load.
Jam A technique used in climbing to enable one to make progress
by lodging a fist, foot, body or finger into a crack.
KN Kilonewton. A Newton is a metric unit of force, mass or amount
of matter times acceleration or change in speed over time, equal to
about .225 of a pound of force. A Kilonewton would be equal to the weight
of 100 kilograms or about a 225-pound person. Mass in Kg x 9.8m/s2
Kernmantle Rope construction consisting of a core (kern) of more
or less, parallel bunches of synthetic fibers. These are contained in

Locking Carabiner A carabiner equipped with a sleeve to lock
the gate closed. May be a screw or spring loaded type.
Mantle Technique used in climbing to gain a shelf or ledge. The
sheath on a Kernmantle rope.
Mechanical Advantage A ratio of the weight of the load to the
theoretical force applied to raise the load.
Protection A point of security such as a chock, piton, bolt or
other device where climbers can clip in.
Rappel To descend by sliding down the rope in a controlled
Rig To fashion any system with a rope, webbing and or carabiners.
