How useful it will be to other people who haven't spent years working with the thing it's a guide to is a different question, but at least I have the majority of the important things done.
I've finally figured out what this thing is:
 |
| It's above the exterior doors at work. |
It's a device to ensure that the left door is always closed before the right door. The right door has a lip on it that prevents the lock from being damaged, but would prevent the left door from closing if the right closed first. However, due to "the device," if you open both doors at the same time, the little wheeled bar falls down, as the metal plate on the left door is not there to keep the pawl on the device has nothing to keep it up. The bar then prevents the right door from closing fully, so the left door should be able to slip in under the lip. I don't think the leverage is sufficient for the left door to then force the right door back open enough for the wheeled bar to be free, but it's still kind of neat.
And to think it only took me like four years to sort out what it does, other than make a "clank-clank" sound when you open the door.
