we need some construction person to tell us what this is and is it common.

One person on twitter said it was probably on a retractable safety device but not sure this is what that is.

i am not sure this is the actual picture of the noose. the site doesnt make it clear. Some other sites with descriptions differ from this..a rope with a noose at the end.
