interesting padlock

[erehwesle]

A friend of mine, that works for DLA here in Philly and who knows of my intererest in locks pointed me to a website with a very interesting padlock made to DoD specs required to be used by US mil in high security applications. They look quite interesting.

Of course, I can't get my hands on one, as I'm not in the millitary, and in the current security environment it isn't wise to inquire too deeply, but it is interesting to speculate what security features the lock may have. It has a well guarded shackle, however the picture doesn't show what the key looks like.

I also, just out of paranoia, really don't want to directly link to the picture from this website. But the lock is called:

S&G 833C, Padlock, Key Operated. High Security Shrouded Shackle

and a Google search will bring it up as the first hit. Its on an open website, though there is a notice that only DoD personel can purchase one of these.

And to all of our friends out there keeping America safe, let me emphasize that as a hobbyist picker, and lock enthusiast, I would *never* attempt to pick a lock I didn't own. I'm strictly interested in the fascinating theory and craftsmanship of various kinds of lock construction.

Anyone ever see one of these in person?

Ah, I've browsed that padlock before. It costs $178!!! Guess where taxpayers money goes, eh?

I think the main thing that is special on this kind of lock is a restricted key profile, so nobody can easily obtain blanks, duplicate existing keys, or file another key to fit.

But it opens with a key, so assume it can be picked, though perhaps not with ease.

Pheniox might be in a position to know more, since I believe he works for the military.

Looks pretty gnarly though, with all that shackle shrouding and the cool gunmetal grey body. I know if I was a Bad Guy I'd be rather intimidated.

So is that not the key at the end of the .pdf?

The lock uses a standard medeco core, and is rather easy to pick if you can pick medeco's in general. They actually come in two keyways, one that is restricted to Military Only and the other that is for Military Contractors. I have been able to aquire about 3 of these and have dozens of the predecessor the S&G 831b. I recently got some spare cores for the locks as well.

An interesting thing to note about the 831B's is that there are essentially two versions, the first release was not key retaining, but when the Feds changed the requirements to require a keyretaining lock, S&G released a retrofit kit to make it key retaining.

These locks are interesting.
I bought several from the DRMO a few years back with one key. Well used for $10.00 @
They come from S&G with one key + a ‘control key” to remove the core. There were several different manufacturers, Singer ( of sewing machine fame) made some for a while
They are real brutes.. explosion proof/ pick proof/ drill proof ect. they are commonly used on ammunition containers. The locks themselves weigh about 4 pounds each and have a hard steel body, some have a shroud, with a rolling shackle that prevents sawing.


Lockmasters? maybe Mark Bates was selling them a few years back for $250.00 for the open shackle and $500.00 with the shrouded shackle.

That is a lot of $ for a padlock.


Erehwesle, hold on to that lock you will be glad you did, you will be only person on the block with an explosion proof lock, who knows you just may need it someday

Nice lock. Interesting design. I guess what you are paying $170.41 for is all the brute-force protection. Hence, nothing i would pay to put on my school locker
