I found 1" brass 'O' rings for $0.99 each that are rated at 500#. I am planning on using these for the ring buckle suspension for my 2 daughters' hammocks. I was thinking about using these as well for the tree hugger to loop my webbing thru instead of a Dutch Clip, would the 500# be acceptable to hold me at 230#? Should I double up on the rings to increase the strength? What are your thoughts?
