I had trouble installing these the first time on my new Warbonnet Ridgerunner. Rather than risk damaging a tarp, I was planning on replacing my original RR dog bones in order to use these bridge hammock buttons. However, the second attempt to install worked out and I now have a trouble free Ridgerunner.

It's a shame folks have poked holes into tarps but at least now there is a cure. Hopefully Fugal's buttons will be offered by companies who manufacture bridge hammocks.
