That Little Hole Next To The Elevator Is Very Important
If you’ve ever been standing to wait for an elevator for an extended period of time, you may have noticed a small hole in or around the door. No, this isn’t a peephole to look through, it’s technically called an escutcheon tube. With a proper key, it is used to open the doors of the elevator whether the actual elevator cabin is there or not.
This way, maintenance workers have easy access to perform tasks such as cleaning and inspection. Or in the unlikely instance that you get stuck in the elevator, people have a way to open the doors and get you out safely.
