Heavy Duty Pulley and Fasteners-Need Help Indentifying

Whoa....I only found the screen capture, had no clue this was a vid.  Pure Gold.



Is it just me.........or is that G- Whiz?!?!?!???????!!!!

O......M......G......I didn't want to say it.........

Looks like maybe a safety lanyard. I was an iron worker in the eighties in Atlanta, pictured is me at 20 floors above Peachtree and West Paces Ferry rd, with a working clip, the clip we use to work columns, sometimes we used ones that had a longer line, so you can walk around still, and it has a built in extension so you don't get yanked when you fall, but it sure hurts.  Me and another guy got knocked off a beam by the crane at 24 floors, swinging in midair, we had those on, it ripped my side open when it stopped short at a dozen feet or so.  I shit my pants. Saved our lives. They throw them away after a while, they get dirty, greasy, cracked.

 
  Yep, fall restraint safety gear.  The thick part, during a fall acts like a "Shudder"
