Unidentified Remote Combination Viewer Vaults

If you look closely there are two indentations on the glass door frame which leads me to believe a security bolt was also used there as well.

It's highly unlikely they're using those security fixing bolts tbh- those parts are going to be purpose made for that door.

Don't forget that 2-point configuration has been around in industry for donkeys years and it's still used on fixings today on bearing retainers, spindle locks, annular rings, guide sleeves etc.
In many applications it's actually the only way when parts are flush or recessed and flats or hexagons can't be applied.

In fact you should recognise the two holes and associated wrench if you've ever changed a grinding or cutting disc on an angle grinder- Its still the most common method of tightening the central nut.

The adaption to standard sized bolts and fixings available off the shelf as 'tamper resistant' is relatively recent in comparison, and any machined pin or similar part with 2 holes will of course look exactly the same when viewed from the end.

Here's another side view where the alternated anti-drill dowels are just visible down the door edge- that's one thick door!

What material would they use in anti drill dowels.

[VaultDoors]

This may be an optical illusion but the vault door appears to be a lot thicker/deeper than the door frame/wall thickness...



Also, I do not see and bolt marks where they extended and rest against the interior frame. It almost looks like this is a transplanted door and grille from a former bank to someone's man cave. Not what I would expect from a typical bank installation from the early 1900's.

The red arrow points to where the locking bolts lock into the frame. The day gate is always been there as far as I know. The ramp is down in this picture so the door can't close. TJ

I have stumbled across many Remote Combination Vaults (without viewers) in my quest to discover all known Remote Combination Viewer Vaults. Remote Combinations (and bolt-throwing handles) are either flush-mounted on the door jamb or surface-mounted on the door jamb in a case with illuminated combination dial(s) and a pressure system lug. Check out the Remote Combination Vaults album.

All Remote Combination Viewers either have a pressure system lug like One King West:



or serve as the pressure system lug lock like the Cleveland Federal Reserve:

Wow guys, those are fantastic pictures! Keep posting more :)

What was the pressure system use for on these vault doors?
Why are the early doors round and the later doors rectangular with the pressure system?


How is this vault door locked or unlocked?
