American LockA5360 2" (51mm) Shrouded Solid Steel Keyed Different Rekeyable Pin Tumbler Padlock

I want to start off by saying this is a great lock. It’s thick and sturdy. No one will be breaking into your stuff using it. That said, I wish the shackle came out of the shroud/body just a little higher. I bought this to lock a 20’ Uhaul truck because I was going to have to be in a hotel for a few days and didn’t want anyone stealing everything. The lock went into the truck door latch holes just fine. However I couldn’t get the lock shut because the shroud was in the way. If the shackle had come up out of the shroud (while unlocked) just 1/8 of an inch more, I’d have been able to turn it and shut it. So just be aware that if you need to lock something and the latch is thick, this lock may not work for you. I’m keeping the lock. It’s a good lock and I’m sure I’ll use it for something else down the road.

This is the hardest solid steel, 3/8" shrouded-shackle padlocks I have found, and for just $50 it's an absolute bargain. Highly regarded by the renowned LockPickingLawyer, it is virtually unpickable by anyone short of an expert, and unbreakable compared to any comparably-sized chain. The A5360's 3/4" internal width and 3/8" shackle diameter is a perfect fit for an Abus 6KS Square Security Chain, which fits snugly without binding inside the lock's shackle compartment, blocking access to the shackle by bolt cutters. A six-foot Abus 6KS chain plus A5360 lock weigh less than 5 lbs, not too heavy for a city bike and long enough to shackle both wheels. For significantly more security and reliability than this, you'd need to step up to a motorcycle chain of more than twice the weight.

BEST.LOCK.EVER. This is the best $ ever spent. I had my locker broken into on multiple occassions with a Master Lock I had; I talked to a co-worker, who happened to be a locksmith in college, and he suggested this one. It CANNOT be broken into as I know from experience: I accidentally locked my keys in the gym locker and when they tried to cut it with lock cutters - about 12 different HUGE guys attempted - it barely left a scratch!!! Someone would need a miracle to get into this. Definitely recommend for everyone

The lock is solid, clearly well made and a good value for what you get. Just look at YouTube reviews about it.The issue I ran into is that I intended to use it in conjunction with a 3/8" (10mm) Laclede security chain. Unfortunately I could not get 2 end links of the chain to fit into this lock. The shroud prevents the shackle from closing when the 2 links are inserted. So if you intend to use the same type of security chain, this is not the lock for you. Otherwise, go for it.

I'm not going to comment on the security of them lock cylinder vs a lockpick. Your can find that info online. What I will say is that this would be difficult to cut and has stood up to rain for six months and locks and unlocks smoothly and easily. It's very much a deterrent to a would be bike thief.

One would think that paying $50 for a lock would mean the keys it comes with work. In this case the lock comes with two keys, but only one of them works. Now I have to go to a locksmith to duplicate the good key. Very disappointing.

Very heavy duty lock. I use it to lock the front forks on my motorcycle

Bought to lock our 26’ uhaul and it can’t fit around the lock.
