2. Tensionless hitch - Wikipedia

   en.wikipedia.org/wiki/Tensionless_hitch

   A Tensionless hitch is an anchor knot used for rappelling or rope rescue. Unlike most knots, the tensionless hitch retains a 100% efficiency rating, [ 3 ] meaning the strength of the knot is equal to the strength of the rope; it is not a significant stress riser .

3. Carabiner - Wikipedia

   en.wikipedia.org/wiki/Carabiner

   Center is a standard carabiner rating. Using a carabiner to connect to a rope. A carabiner or karabiner (/ ˌ k ær ə ˈ b iː n ər /), [1] often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate [2] used to quickly and reversibly connect components, most notably in safety-critical systems.

4. Kernmantle rope - Wikipedia

   en.wikipedia.org/wiki/Kernmantle_rope

   Kernmantle rope (from German kern 'core' and mantel 'sheath') is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the core from abrasion during use. This is the only ...

5. Radium release hitch - Wikipedia

   en.wikipedia.org/wiki/Radium_Release_Hitch

   A radium release hitch is a load-releasing hitch using 3:1 mechanical advantage which is used in a two-rope technical rescue system. [1] The Radium Release Hitch allows a load to be transferred from one rope to another and is commonly rigged into the belay line prior to the operation of a two-rope technical rescue system.

6. Climbing rope - Wikipedia

   en.wikipedia.org/wiki/Climbing_rope

   A climber and a belayer using a climbing rope. 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.

7. Dynamic rope - Wikipedia

   en.wikipedia.org/wiki/Dynamic_rope

   Unlike most climbing equipment, dynamic ropes do not have a rated tensile breaking strength. Instead, the strength of a rope is tested by the number of standard test falls a rope can sustain before breaking. The test falls use an 80 kg weight for single ropes (55 kg for half ropes), and a fall factor of 1.7 (4 meter fall on 2.3 meters of rope ...
