Most Formidable Combi Pad-Lock

[MichelKS]

Hello,

I'm no lock-picker, so I'm probably not going to be much help to the folks on this forum: forgive me for my effort to selfishly knowledge leech from the pros


With that said, I'd greatly appreciate knowing what lock-pickers consider to be the most formidable combination pad-lock.
That is, the pad-lock you consider to be most resistant to cutting (or any other type of forced entry), and picking. The lock is being used outside, so it needs to survive the elements.

From my research, I've identified the Squire SSC50 as the best candidate. http://www.squirelocks.co.uk/pdfs/squire_stronghold_ss50combi.pdf

Is this the most formidable, weather-resistant, combination padlock in existence - or should I keep looking (and if so, for what )

Thanks for the help

I don't know if it is the best lock ever, but it does look to be a good lock.

Squire in general does make very good locks.

I would sleep well relying on a lock like that.

I'd go for the combi you've linked to. I think it will serve you well.

If it's the "most formidable" combi lock remains to be seen, but it's excellent quality. One judge of if a lock is vulnerable or not is to check what's on youtube for it. If there's a way for it to be bypassed, it usually doesn't take much time for a vid to show up for it.

Some combination padlock locks have a steel ball inside the combinationdiscs (I mean the discs which have the numbers on them, the ones you turn) and I think they prevent shimming-type decoding attacks.
I'm not sure the squire has it, I don't know that model, but it would be a nice feature.

Makes sense. I went on Youtube, and didn't pull-up anything.

Noted. Thank you.

Is there a term for these steel-balls? Are they usually listed on product spec-sheets?



I should have considered the shackle's clearance. The Squire SS50CS has a 15mm vertical clearance, and 16mm horizontal clearance.
I assume that means this lock could not accommodate a 19mm security-chain (link to product at the end of this post) - unless there's something that I'm missing, or that I don't understand.

So, if the SS50CS won't accommodate the chain, then what combination pad-lock would you recommend using in its place?

IF you want a tough padlock, Master Lock Pro Series # 6721 WO. This is a "door hardware" type of lock, which can take most any KIK cylinder. Key it to your existing and you are set.

The shackle is surrounded by a shroud, which is cut proof. It has two 3/8 stainless steel balls which lock the shackle in place. It won't shim, rap, or otherwise be forced open.

IN the package, you get everything sub-assembled. Provide your own cylinder, then just follow the instructions int he box and screw the thing together. We sell these things to vending machine people who need something which some jerk can't just waltz up to with a bolt cutter and remove.

6721 WO - Body width 2 1/8" Shackle clearance, 3/4" -- shackle dia. 5/16"
6727 WO - Body width 2 5/8" Shackle clearance, 3/4" -- shackle dia. 7/16"

The "21" should run you about 49.00 (US) less cylinder.
The "27" should run you about 68.00 (us) less cylinder.

Combination padlocks unless you are talking an S & G government unit, are useless. ALL can be worked out in time - and most can be forced by one or more methods.

Regarding this question, my answer is: ABLOY PL362 with the Protec locking mechanism, see e.g. http://securitysnobs.com/Abloy-Protec2- ... dlock.html

I think he only meant combination locks.

I otherwise I too think the PL 362 is the most formidable readily available padlock I know.
Well maybe the S&G 833 is stronger. But it's price is quite restrictive. Maybe the protec core is harder to pick and the S&G is more physically resistant.

I'm not really sure this is as much a question as a statement.
