Cable Locks

Postby mikewhiskeyhotel » 18 Jun 2006 15:24

I have a cable lock, the cable when inserted passes through two wheels, this locks off the cable. Has anyone come across these before ??

Is there a way that you could post a picture of the described lock? I'm not really sure what kind of mechanism do you mean, but it does sound intriguing.

Cheers,

This sounds very similar to the Masterlock Python lock. Perhaps this is what you are describing?

Right, those aren't locks and they aren't intended to keep people out, just to record an entry. They're generally used for international shipping, where the serial number is recorded on the bill of lading, and the seal is checked against the number when it arrives at it's destination port. Simmiliar items have been used for treaty verification during the SALT and SALT II talks. There's not really any reason to be "bypassing" those, as the ability to d so would be of interest primarily to dealers of illegal weapons, drugs, and human traffickers.

Thanks for that, my company have been using these on Trailers, we have had quite a few turned over, trouble is there is no forced entry, having looked at the lock sorry (seal) myself there is no evidence of tampering. Although new at this and getting proficient at conventional locks, I am aware that no locking mechanism is 100%. Apart from changing these it would be nice to know how its done,but I am confident I'll figure it out eventually.

We wont say how they can be compromised on here but if its any help.......

They are likely cutting them off and resealing them, get your boss to mark them with ultra violet ink to see if this is so,

Well they can be compromised and reused but i think replacement is more likely.

When marking them make sure its secret as well as i suspect its an inside job.

better yet tell your boss to find seals that cant be reused a second time. We use a one time use seal where i work and all of the containers that come in from over seas also use a very heavy duty one time use seal that cant be taken off without bolt cutters.

If I was your boss Id be checking on my insurance policy to see if he is covered using such a seal as what you have shown. I honestly cant see the point of using one like that for any purpose.

Tamper-evident seals

Postby mh » 20 Jun 2006 9:46

It's funny how badly some "tamper-evident" products are made.

When our child was born, he got a tyvek wristband that was supposedly tamper-evident, so that we could be sure we had the right little guy :)

Of course I removed that band carefully as a keepsake, but it's not visibly broken, and I could easily place it around some other child's arm.

Nearly no added value in terms of protection against tampering :(

Still we are sure we brought our own baby home :lol:

This comes from an episode of CSI:

If you are worried about someone taking off, messing with, and resealing something like this, take a photograph of the "lock". Comparing the photo with how the "lock" looks when the shipment is received will also reveal any tampering. This depends on the type of "lock" used, whether it will work or not.

How so? Does he keep a pair of Bogota's tucked in his pampers? Like father, like son, hmm? :)
