Here is one that we service, still in use.

This series 5 star was before the Constellation.

That looks like a match with the Drury Plaza doors. I didn’t realize there were 5-stars before the Constellation.

I also noticed the door seems to include a switch where it meets the doorstop and I assume this tells the opening mechanism when to stop.

Half right, it’s tiled Hydraulic Cushion stop, but also disconnects the electric motor for the hydro pump.

Perhaps the device under the Cleveland Federal Reserve vault door is a hydraulic cushion stop:

In my search for Combination Viewer Vaults I have discovered other jamb controlled vaults without combination viewers, some with and without pressure housings. Here is an inventory of jamb controlled vaults without combination viewers. Please let me know if any additions or corrections are needed, thx.

Why are there large gaps between 100 and 0 on the combination dials? All combination dials are different except for the number gaps.

Why do some pressure system lugs have a short slot while others have a long slot? Also, how are the roller racks used in the pressure system?
