Phil, participants at high ropes courses,as you say, shouldn't climb above their anchors but they do, every time, that's just how people are. The only way to avoid it is to not have vertical climbs in the course design. That's the way I do it. Or, if there must be a climb then it is rope belayed.
BTW the wire rope, cable, is usaully: 10mm 7x19 20/70 grade galvanised aircraft cable. |
