Static rope

A static rope, or a semi-static rope is a low-elongation rope that is designed to stretch minimally when placed under load; typically less than 5%. In contrast, a dynamic rope is designed to stretch up to 40%. Static ropes have a wide variety of use, for instance in fire rescue operations and caving.

Static ropes have some applications in climbing, such as for hauling gear, abseiling, and top-roping in some situations.

Lead climbing is always done with a dynamic rope, since a fall on a static rope would be stopped too quickly and could lead to serious injury.

Rated static ropes usually conform to the EN 1891 standard split into EN 1891 Type A, and EN 1891 Type B. Type A ropes are intended for general use due to their superior strength; wheras, type B ropes are intended for use in specialised circumstances where the usually thinner diameter and lower weight are critical for an operation.
