Edge protection is a vital piece of the rope rescue puzzle but it is often overlooked or done improperly. Over the last 15 years of teaching rope rescue and working for a department that gets our fair share of high angle calls I have used almost every type of edge protection out there… most leave little to be desired.
Now their is a difference in wether you are doing a rope rescue in a urban setting (off of a crane or off an apartment building) or weather you are operating in a wilderness setting. If you are working in an urban setting the rope protection is fairly easy, a couple small rollers and you are set. But in a wilderness setting it can be slightly more difficult, the rope has several different rocks, tree roots, etc. that it can pass over. Several years ago I was shown a homemade version of edge protection that is still the best I have used to date.
The edge protection is made using small diameter wood dowels that are strung together with some old 6 millimeter cord. The dowels are cut to length, drilled, sanded and then they are ready to be assembled. Small sections of clear water pump tube can be used as spacers on the ends to keep the dowels spaced.
