Choosing your rope wisely
Types of ropes
Dynamic ropes
Single ropes
Ropes used as a single strand. These sport climbing ropes are mainly used for single-pitch climbing or on easy mountain terrain. Some climbers also use them for multi-pitch climbing.
Half and twin ropes
They are certified according to two types of standards: half and twin.
- Half ropes: ropes used in pairs that may be clipped separately during progression. They are recommended for rappels and to facilitate rope drag management. They provide extra safety in case one of the strands is cut by a falling rock or a sharp edge
- Twin ropes: ropes used in pairs that, unlike half ropes, must be clipped together during progression. They are recommended for rappels
Low stretch kernmantel ropes
Low stretch kernmantel ropes have low elongation and are very resistant to abrasion. They are designed for caving, canyoning, rope ascent or hauling, as well as for bolting a route.
Manufacture, finish and treatment: Petzl’s choices
UIAA Guide Dry Treatment
The UIAA Guide Dry treatment is our most complete water repellent treatment for frequent use in wet environments. It makes a difference especially for regular use in extreme environments: ice climbing, mountaineering. This treatment also improves the rope’s resistance to dirt and abrasion.
The UIAA Guide Dry treatment meets the requirements of the UIAA Water Repellent test. The results of this test indicate water absorption of less than 2 %.
The manufacturing process for UIAA Guide Dry treatment has two stages: the core is treated before the rope is braided, and then the entire rope is treated in order to minimize water absorption and penetration of fine particles into the rope.
Duratec Dry Treatment
Dry treatment, making the rope more resistant to water, dirt and abrasion. Handling, grip and other characteristics are retained longer in cold, wet conditions.
EverFlex Treatment
Special treatment stabilizes the core strands and improves consistency. Provides excellent grip and handling over time.
UltraSonic Finish
Ultrasonic welding bonds the core and sheath together at the rope ends. Gives greater durability and avoids frayed ends.
ClimbReady Coil
Specific coil makes the rope ready to use. Helps the user avoid initial uncoiling mistakes, and increases longevity.
Middle Mark
Indicates the middle of the rope to facilitate maneuvers.
