USE A DAMPER
Before tensioning the rope or cable, attach at least one damper to the line. There are two possible hazards: either the cable snaps and acts like a giant whip, or a hook or bow shackle fails. With that in mind, best practice is to attach a damper in the middle of the line and a second damper as close as possible to any metal components. If you’re in a bind, then a heavy jumper, a tarp, Driza-bone or a towel will also do the job.
