A double runner used to equalize two anchors.
Note that you must secure each side of the sling with an
Overhand on a Bight (step 4) in order to prevent a
shock load should one of the anchors fail.
Double runners are twice (or three times) as long as single runners and are used mostly to string
together belay, rappel, and top-rope stations. A couple of these are usually adequate for any situation.
If you use your long runners primarily for top-roping, make them from 1-inch tubular webbing, which
cuts less readily than the thinner stuff.
