  1. The aluminum swage ferrule should be properly compressed and not hammered flat as illustrated. While ratchet straps may work in some applications for temporary use, they are a dangerous substitute for rated slings or a rated anchor. 1/4" cable may be appropriate for very young children, but it will not suffice for heavier participants. If riders will be more than 3’0" off of the ground, fall protection including helmets, harnesses, and rated lanyards should be worn.

    As a professional builder, I would advise backyard enthusiasts to google "zip line accidents" before undertaking this project. There have been far too many backyard zip line accidents and fatalities in recent years that could have been avoided by a little professional guidance. Also, I would recommend carrying general liability insurance if the end-user intends to have anyone other than their immediate family ride the line. Having been called upon as an expert witness in several backyard cases, building a line to this design will offer you no protection… and you’ll probably need it.
