IDK what's going on and why, but bolt cutters would work 😆

Sometimes you roll up and there are like 6 locks daisy chained and you know 1 combo but not which lock your combo works on. It would be faster to cut a link and add a lock than try every lock with your combo.
Of course then there are 7 locks and it becomes an even bigger time difference for the next guy.
Didn't realize people daisy chained locks. I take it this device allows for same 1 of N use, but not obvious how from just looking at it. Guessing removing a single block allows slider to move enough that one can detach
Yep, the goal here is 1 of N shared access to the location with N being however many of the vertical blocks you have.
The bit to the left with the chain on it has a C cut into it if you look down from above. Remove any one lock and you can slide the other verticals to the right enough to pull the chain out towards the photographer.
I realized after I left I should have taken more photos to show the clever mechanical trickery so that the upside down bars are full time locked when upside down but if you pull any other lock bar you can flip it and add a lock to do an N=N+1.
If you are a paranoid like me it is a moments head scratching how to ensure you can't be locked in by someone else while working. You have to take the vertical bar that you removed with you to go do your work.
I see, somewhat what I was guessing. I'm most blown away by this daisy chain thing. Never seen it in the wild, but don't exactly "work with my hands".
Clever to keep the bar in hand
Super common for infrastructure locations like power plants and radio towers, remember I do #hamradio
My day job is keeping my office chair from floating away same as you.
Oh, you've just reminded me I should check out my local ham meetup. Think there's one very soon (they're infrequent). Will report back if I go
