Cisa 57110

Here is my newest lock from eBay, a Cisa 57110. It would be nice if you could tell me what kind of mechanism this lock uses. I believe it is a complex warded lock. Anyways, poorly lit pictures are below.

I'll probably get around to mounting this lock once I find a decent piece of wood for it.

A 6 and 5 lever:

it looks like a lever lock to a certain extent, but im not sure...

What was that lock securing?

It came new in the box. It's almost like a safe lock, since the exterior keyway is so elongated.

It's a safe lock.

And also one of the lever kind.

I COMPLETELY forgot about that lock! I was watching it back when it was in auction but neglected to bid on it. Now I'm kind of mad at myself, that's a pretty impressive lock!

You would have to pick the lock 4 times to fully withdraw the bolt. Once it moves forwards a bit it'll stop and settle up against the next fence. Seems like a good challenge.

I went dumpster diving last night and found a nice, thick piece of wood to mount all of my HS locks on. I don't have the board painted yet, and it doesn't have a base either. Tonight, I mounted the Cisa. I plan upon mounting my Miwa EC deadbolt tomorrow, that is, if I can find that darn hole cutting drill bit.

Notice that I stripped most of the bolts on the back, that is because the hardware wasn't very good.

It's a lever lock, however, for some strange reason this particular type of lock is designed for house doors, not for safes.
cf. http://www.cisa.com/flex/cm/pages/Serve ... agina/1920

Apparently, some Italian customers are afraid that someone might use a saw on their deadbolts, so they have 4 bolts...

I've seen similar locks actually mounted in Italy; IMHO it was some kind of overkill for the not-so-strong wooden doors they were mounted on

Yeah, in Florence they have those all over the place on shop doors...

They are quite easily opened with the correct tool :wink:

So there are no criticisms about my installation?

No, think you did that as well as any Italian carpenter could do that

It's certainly a lever lock. The double bitted key is similar to those found on safes, but the lock itself is not. Against brute force, this is probably a very good lock, but against anyone who can pick a BS lever lock this isn't going to be a big challenge, once a centre tensioner is made.

The double bitted key is symmetrical, which reduces the security, as it only needs decoding once, and there are no anti-picks. Properly equipped, I'd rate these as ten minutes at most, NDE.

I'd feel bad for the idiot that might try to kick that door down :mrgreen:
