CHOOSING A CLIMBING ROPE:

 

Single Ropes: The classic rope for climbing. Depending on their diameter and length, they can be used in most areas. The main advantage is simple easier handling.

They are ideal for cliff climbing or indoor climbing. Designed for single strand use, it is not recommended to use with two strands when climbing (at the risk of breaking your back in the case of a fall).

Single ropes are available in diameters ranging from 8.7 to 11 mm, weighing between 51 and 77 grams per meter. They support in a single strand at least five standard drops with a weight of 80 kg.

Double Ropes: Also called a rappel, double ropes have a "1/2" symbol on the label. They are used in pairs, which allows you to go down the same length as climbed.

Made up of 2 strands which the leader is tied into but, unlike twin ropes, two seconds may each be tied into just one of the strands. Each strand is normally a different colour to facilitate the clipping and to know on which side the knot is to get back the rope.

They are used on both strands, but it is possible to clip only one strand at each point to reduce the impact force during a fall and to limit the drag.

Double ropes are fine and light, between 8 and 8.5 mm diameter and between 40 and 50 g/m per strand.

Twin Ropes: This rope is always used with the two strands together and remaining parallel. Each climber ties into both strands, and these are always clipped together.

The two strands provide redundancy in case one of the strands is cut by a falling object or sharp edge. They are therefore particularly suitable for mountain climbing or serious events. They offer maximum security and allow a belay the full length of the rope.

With a diameter of 7.5 up to 8 millimetres and a weight of 38 to 45 grams per meter, they weigh approximately the same as the single ropes.
