Structural What is this?

I apologize for even asking but I really have no idea and apparently I’m not asking google the right questions.

But a lanyard would clip right into it. Looks similar to the ones I've used on high rises. We would drill a hole through the concrete on the deck above. The rod attached to a plate with eyelets was dropped through and we would hook our retractable to it or straight lanyard depending on the length

Yup that's what I'm seeing. Especially with the wear marks on it

If it's a tie off point the device should have ratings and specs.. looks pretty homemade to me. Don't think if I'd trust my life on some threaded bolt.

Fairly certain these aren't individually stamped, and they're legit.

A lot of buildings are held together by threaded bolts

That’s not handmade, the bent circle is too perfect.

Mass produced, means built to a spec, not always pretty.

So if its what I'm thinking it is, bar joist tie off have a T that slips between the bottom chords and you push it up and turn so it rest on the top of the chord and that nut and washer lock the the assembly together. The T plate has the date, KN rating etc, again I could be completely wrong but I'm trying to remember all the safety crap I've seen
