Heavy Duty Padlock with 4 Keys - Hardened Solid Steel Hardware Monoblock Lock - 12mm Thick Shackle - Protector Lock for Garage Door, Containers, Sheds, Shutters, Lockers, Gates and Warehouses

I had a case hardened padlock on my gate and they just pried on it and broke the lock. This lock can't be broken or cut through with bolt cutters. This will do the job!

This thing is stout! I was looking for a lock that would fit three 5/8" steel braided cables. This one works perfectly (see photo) and the actual "shackle" is thick like the cables themselves. I didn't want to put a weaker lock around the cables because then it's much easier to just cut the lock than the cables.With this lock I'm confident that cutting either the lock or the cables will be tough. Not only is it very sturdy but the design also allows the shackle to freely rotate when it is locked. This makes it even more difficult to use a saw or some other device against it since the shackle will spin.The lock is very heavy and also has the added bonus of coming with five keys.

This fits easily in the shrouded lock on a standard container, and presents the key slot downwards. The keys are somewhat larger than I expected, about the length and thickness of a house key but approx 1/2" wide. I chose this lock because it doesn't have a giant overmolded grip on it and so blends in more easily on my everyday keychain. Of note, the key only turns about 1/4 turn before unlocking. When turned, the shackle shaft 'pops' out towards which is an interesting and kind of nice feature. Perhaps because of this ejection, they didn't include a knurled extension to the shaft to pull on. Hopefully this doesn't cause problems later with rust, as you wouldn't be as able to coerce the shaft into moving when frozen. Similarly, when locking, you can push the shackle shaft inwards to close the lock, and in doing so, your key is turned back to the starting position and can be removed. You can't remove the key with the lock unlocked. I subtracted 1 star because I would prefer the shackle shaft had a knurled extension to pull on, and also because it only comes with 4 keys, whereas more would have been very helpful. The key is too novel a design to be copied by a keysmith (I believe)

I used 3 of these on a 5x8 uhaul 2600 mile move. They worked well. The pin / shakel fits perfectly into the 5x8 uhaul latch although you'll have to bend the uhaul's latch tang slightly to close the lock. I used the other two to secure each end of an 8' length of hardened 5/8 inch tow chain to ensure that even if the trailer was poped-off the hitch it couldn't be separated from the car and stolen.Be sure to duck tape the keyhole as the tumbler DOES RUST after 1 rain

They are not rusted and they always pop open. The paint looks almost new. Where I live, Top notch, "Locksports", do not come out at night, stealing well used garden equipment. Parolees and drug addicts come out stealing, as soon as it gets dark. Years later, no problems. Key does not come out, until you resecure the lock. Helps keep the key from getting lost.

Love it. I use it to attach my side by side to metal post!

Bought this to practice on, noticed the keyway deforming under minimal pressure. Within a couple of minutes I was able to snap the front of the keyway out and bypass the lock completely with a small multitool. I would imagine the same could be done with any decent standard screwdriver.If you want a big heavy lock to say "wow this is a big heavy lock", this is for you. I would not secure anything worth of value with this.

Seems like a very stout lock for the price. Has some decent weight to it and the locking mechanism is smooth like butter although I will still be greasing mine. Looks hard to break by the size of the shackle! Time will tell as always but, I do have a piece of mind now that my stuff is locked and the size of this thing would probably scare a theif lol.
