Hi – as the title says one anchor [ the far leg of the y-hang ] Was found to have movement when I de-rigged it – not excessive motion just a little wiggle , It was firm to touch when I rigged
Here is an pic :

And my pathetic attempt at a riggers topo :
From right > left [ as I remember it ]
1 – evil rusty spit [ unused ]
2 – huge boulder that I used to back up everything
3 through bolt with peztl hanger
4 unknown bolt – formed the right leg of the y-hang
5 the loose hanger
6 – a hanger @ low level
The offending hanger is Some sort of through bolt with a “dee hanger “ very similar to :

So I suspect a few seconds with a spanner will fix it – plus re-inspect after load
But Having no spanner – there wasn’t much I could do at the time – but now I am home – I can talk about it on the internet – so at least others will be aware
and know to take a spanner
