.Single ropes – for climbing with one rope.Twin Ropes should be used in pair and the ropes should be of equal length and diameter.Half ropes – for climbing when it is a must to use two ropes. Half rope technique uses “left and right“ rope. These ropes are quidded separately through different belaying points.UIAA is a registered mark of the international climbing federation UIAA (International Mountaineering and Climbing Federation). This symbol can be used only for the products that fulfill the strictest safety requirements specified by UIAA.UCE - The Ultrasonic rope ending in the form of a compact cone is in a very distinct manner improving the quality of the rope ending so there is no rupture of sheet from the core on the ending during the use of the rope.Fixbond - The technology of connection of the core with the sheath along the entire length of the rope. Optional.Ultra Deep Protect – UIAA water repellent. The system of PFC-free in-depth treatment of core and sheath yarns that increases the water resistance. It prevents the penetration of dirt into a rope and increases its abrasion resistance. Water resistance level measured in accordance within the UIAA methodics is 1,0% - 2,0%.ITT – Infra Thermo Treatment is a stabilisation of sensitive structural balance that gives our ropes a perfect handling.Coloured middle marking of a rope for better orientation while rappelling.CTC – Continual Tension Control secures a guaranty of the most important parameters like the number of falls, impact force, sheath slippage, knotability in full length of the rope.CE 1015 certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The number behind the mark CE (1015) indicates the competent authorised laboratory.
