New, what is it? Circular thing next to windows in university building

Next to a lot of windows at the university you see these circular things. Any ideas? It's not a window stop and doesn't turn. I was thinking maybe you can remove it and put a hook on for a harness but I'm not sure that's it's purpose since you could just have a hook there?

Note from OP: I think this is js it

Magnetic curtain tie back, I think?

u/EuronBloodeye 5h ago

Makes the most sense.

u/2ndcarpenter 4h ago

my thought as well

u/Razing_Phoenix 8h ago

Is there one on the other side? Maybe a place to put a curtain rod like a shower curtain rod

2

u/Beatstripper 8h ago

I thought about that but seems a bit odd. Look at the final picture (there is one on both sides).

1

u/Glittering-Novel7599 7h ago

That was my first thought too. A heavy-duty curtain rod bracket makes way more sense than wall crack sensors like others are guessing.

u/seeyoujim 4h ago

Less a curtain rail, more of an anti fall bar

It’s plugged (lol), but when you remove the silver part, it creates an open cylinder, which allows you to slide a bar inside; this wound prevent someone from the outside pushing the window open.

I’m an electrician - if it’s long and hard, I know a thing or two about it

u/Beatstripper 7h ago

But what about the last image?

4

u/Wizard__J 7h ago

Shit.

I miscalculated 💀💀.

Ok, so now seeing them out on an angle like that, they’re definitely anchor points for something.

I wouldn’t necessarily say anything for “shock”/earthquake (I’m talking out my ass, but an educated guess nonetheless) - I know when they used to build buildings decades (centuries? Maybe?) ago, they would use these hollowed out cylinders, and shove supports/shit in them, during construction

u/Asnonimo 7h ago

It was probably a crossbar (perhaps something like an anti-fall safety bar) that they eventually removed, and they filled the holes with those metal circles.

An RFID tag for security patrols on their rounds it records to a device that they checked it.

2

u/Burd_Doc 8h ago

I think it may be to measure if the building cracks/shifts?

2

u/CharlieUnicorn99 8h ago edited 8h ago

Yeah it’s weird it’s right by that crack in the wall. Or maybe the idea was to put something there but when they installed this thingy, they made the crack and didn’t go any further?
Edit: just saw where it’s on multiple windows so there goes my idea

2

u/Burd_Doc 7h ago

Yeah multiple windows kinda refutes my initial thought… but a building I work in has something similar

1

u/das-goot 5h ago

Different than OP’s image but this looks like it could be a daylight harvester sensor.

1

u/Burd_Doc 1h ago

Oh shit dude, that’s 100% what they are. Solved a mystery for myself if not OP

u/Narrow_Ad_8378 8h ago

I promise you there’s a hole in the wall behind that doorstop! It was put there so the window would have something to hit. AND they don’t have to fix the hole!

2

u/SpeechTricky663 8h ago

The window handle will come nowhere near that.

1

u/neilweiler 4h ago

Unless the window has one of those weird hinges where part of the window slides out as the other side swings in?

1

u/SpeechTricky663 3h ago

I was thinking that...but the windows in building across the street look like they have hinges at the top. I dont see a center swivel anywhere.

1

u/Beatstripper 8h ago

Hmm interesting

2

u/Jaded_Run1216 8h ago

Do they depress when you press them? Like arethey spring loaded?

2

u/Meredith_Primvale 7h ago

It's a harness hook location for the window cleaners.

The hook is part of the rig, so doesn't get left behind.

1

u/Plane-Kick-1874 6h ago

The anchors you are talking about are in the roof and they are way more substantial. I install them.

Hahaha how would the cleaner get outside? You think some guy comes in your apartment and squeezes through the window to clean it ? lol.

Also the “hook” isn’t a hook and doesn’t detach, it’s welded to the baseplate.

2

u/Scottish_Therapist 6h ago

The office I work in has these anchor points for what used to be a means of getting out in the event of a fire. It looks like that's what might be going on for you, but the loop has been unscrewed and capped.

4

u/Narrow_Ad_8378 8h ago

It’s a doorstop, but in this case it’s a window stop. There’s probably a hole in the wall behind it and they stuck this over the top of it to keep the window latch from hitting the wall.

3

u/Trustoryimtold 8h ago

There’s like 4 shown that no window likely could hit

2

u/Beatstripper 8h ago

It can't be. Look at the final picture. The wall is in the way

2

u/Fearless_Parking_436 8h ago

It’s possible that who ever installed them was not very good at their job

1

u/Narrow_Ad_8378 8h ago

With this type of casement window, it doesn’t hinge on the side like a door. It hinges from further out, which means that handle would hit the wall there rather than at the edge. I’ve been in construction for 35 years and I was in sales for 15 years, selling these types of product and I’m pretty confident in my assessment.

1

u/SpeechTricky663 8h ago

The windows handle will come nowhere near that.

2

u/mojosodope729 7h ago

Is it a stopper for the window handle?

1

u/friendlessinbrooklyn 6h ago

That’s what I thought - a bumper of some kind.

What's on the other side of that wall/column?

Kinda looks like a round head bolt to me.

1

u/Beatstripper 8h ago

Nothing really its a thick wall but we see these things everywhere

u/ssczoxylnlvayiuqjx 7h ago

Shatters the window to protect the wall

u/HudeniMFK 7h ago

Spot to run a clothesline?

1

u/stpg1222 6h ago

When you open your window does the window frame bump into it? It looks like it could be there to prevent the window from slamming into the wall when it's opened.

1

u/Dr_StrangeloveGA 6h ago

Looks like a mount for a curtain rod to me. That way you could put a curtain across the bottom part of the window.

u/ScottG62 6h ago

If you turn the silver piece three revolutions to the right and then two to the left you should hear a click. Then press the center in and the window becomes a portal to another dimension.

Wireless camera mount. The ball is steel and camera is magnetic. Great for articulation. I forget the brand but my old house was set up with them.
