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.

Sorry - in the image it does not look suitable as it appears to have a sharp edge, but the blurb says its radiused and suitable for rap/belay.– user5330Commented Dec 1, 2015 at 2:40

I think there is a huge difference between active abseiling, were the rope is not running through the anchor during the abseiling process, and a passive descending of the climber by the belayer. In the latter case, I would be careful with a so-called rap hanger as you pictured it.– tomglabstCommented Dec 1, 2015 at 11:00

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.

1you should also check the hanger for wear. Many rap hangers become badly worn and can cut a rope or break when weighted– user2766Commented Nov 30, 2015 at 16:19
