The ropes are a one-strand system, which makes them fit for any applications where increased risks of the rope getting severed by falling stones is involved. They may be used with rockeries, rocks, perpendicular rock walls, artificial walls and big walls. The diameter of the single ropes generally is 9 mm and higher. As a function of increasing diameter, the strength and number of falls and unfortunately even the weight tend to rise. This is why it is necessary to establish the optimum compromise between rope thickness and weight.
Two coupled ropes of the same type are used at all times, these sharing the same belaying elements. They are a first choice option for traditional climbing activities in the mountains and unstable surfaces as well as wherever it needs to be ensured that the rope does not become damaged by the falling stones and that the braiding is not impaired by sharp rocks. This does not always have to involve mountaineering; unstable surfaces may as well be encountered in obscure rocky regions.
If the ropes are used in pairs (twin ropes) they merely provide standard safety levels. The half rope technology, which involves the "left" and "right" ropes passed independently through different belaying elements, may help to considerably improve the security levels achieved.
- braiding - a set of mutually interbreeding strands
- the core - is either braided (out of yarn) or consists of a bunch of compressed cords (equal number of clockwise and counter-clockwise cords)
- strand - a bunch of threads (generally 1 or 2 threads)
- thread - a bunch of fibres (cut fibres - several partially twisted multifils)
- filament - the smallest rope component (passes continuously along the entire rope length)
