The way the shackle is with the running part on the pin can create roll out. Always put the u of the shackle on the running part of the sling and the dead end of the sling on the pin. Can’t roll out that way if you have slack in the sling and tighten it it can roll the pin out the way your setup. Or if you tighten drop down see a different angle have the operator slack up to move the tip for a better angle retighten then you cant see the pin will never know it rolled out.I appreciate it, I know it don't sound like it, but I do, if I don't see whats wrong, please do tell me, I seriously don't see anything else wrong
ohhhh wait, also, the sling is set up to tighten the pin, pin should be inside the eye, not the working side! been there, done that, keep a crescent wrench handy to break those free when I forget
