If I'm out on the rock and I come across a pair of hangers, how can I tell the difference between rap hangers (the kind you can directly thread rope through to rappel) and regular hangers (the kind that you must clip a carabiner or quick link into)? I would be specifically looking for the rap hangers since without identification they could both be used like regular hangers.
You shouldn't rappel directly off a hanger if any of these is true:
- The rope does not easily fit through the hole (with room to spare)
- The hole's edges are not smoothly rounded
- The material that forms the hole is much thinner than a carabiner
Because all of these increase the change the rope will get stuck or damaged.
