Quickdraw

Runners are used by rock and ice climbers to extend the distance between an anchoring device and the rope.

The most popular method involves the use of an elastic polymer band around the outside of the point of connection between the carabiner and the semi-rigid material.

[3][4] The elastic band is not a load-bearing element, and the carabiner must pass through the dogbone to hold body weight.

Developed in places such as Rifle Mountain Park in Colorado as a safer alternative; steel is much harder-wearing than the aluminum used in normal quickdraws.

[8] Alpine quick draws feature long slings wrapped or folded multiple times to save space on a climbers harness in place of a dogbone.

Two quickdraws. The upper has a solid bent gate for the rope and the lower a wire gate for it.
