Static Rope
A special climbing rope, which does not stretch like a dynamic climbing rope. A static rope (usually 11 mm in diameter) is usually used as a fixed rope (attached to anchors and left in place) for climbing the rope itself with ascenders or rappelling. Static ropes are stronger and last longer than dynamic ropes, but they are not to be used for actual climbing except as a top-rope because their lack of stretch and elasticity causes the force of a fall to be placed on other parts of the climbers safety system, including anchors and harness, and can lead to failure and severe injury.
