All dynamic climbing ropes are made to meet and exceed the minimum specifications set out by the UIAA.
Single-rope: Also called a Full-rope or sometimes a Sport- rope. It is demarcated by a figure 1 on each end of the rope. It can be used in a single strand for the lead climbing.
Double-ropes: Also called Half-ropes or sometimes Trad ropes. They are demarcated by the figure ½ at the end of each rope. The leader must tie into TWO of these ropes. The Second can tie onto the other two ends or in the case of a three person group, each second can tie into just one of these Half-ropes.
Twin-ropes: They are demarcated by two interlocked circles. These ropes are seldom seen in South Africa. The leader and second, tie into both ropes at all times.
