A runner or quick draw (in French: degaine) is a set of two non locking biners and a webbing sling, used to connect a leading rope to an anchor. Runners can be used for any number of other functions: extensions, connections, hanging stuff etc.
Most runners have two different Biners. The one that goes on the bolt usually has a straight gate, and the one into which the rope is clipped has bent gate.
