Without a doubt, the carabiner is the workhorse of any rope rescue team. I recently acquired a rappel ring for under 5 bucks. This thing is real handy, and so far I have found several uses for it.
- Belay anchor plate
- Multipoint anchor
- friction device
- collection point for loose carabiners
With the cost of rope gear, rappel rings are a good item to have in your bag. What have you used rappel rings for?
