American Lock-A1106YLW Lockout Padlock, KD, Yellow, 1/4 in. Dia.

Well made and worked well for my pelican vault case.

I am impressed with the American Lock 1100 series. If you want a good quality lock for protecting your stuff, this lock makes a good choice. No lock is perfect and this lock can be defeated but that is true of ALL padlocks. The goal of this a lock like this is to encourage the bad guys to move on to easier targets or, failing that, slow down the bad guys and thus increase the odds that someone will notice the crime in progress. In my opinion, this lock succeeds in this regard.

I needed a heavy duty locks for my pelican case and didn’t want to buy flimsy cable locks with a lot of play. Also I didn’t want a solid one with a lot of “play.” Did my home work and settled on American’s lock. Am quite happy.You won’t be able to rotate the lock to get easy key access but you can still insert key from bottom (I.e you won’t be able to see the key enter unless you elevate the case). This is actually good for security.Will pony up for a tsa lock when the time comes but until then, things look secure.

Bought this for my man as a gift so ge could get better as locksmithing, and it's bested him thus far. I consider him a pretty good lockpick, and he hasn't cracked this one yet. It's been 7 months, so safe to say your valuables would be in good hands if this was the lock!

Good all around lock, pick resistant.

People should realize that padlocks are very specific security devices; you need to get the proper padlock for your application. I'm stating this, as it's very apparent from reading many of the reviews that people don't realize this.This model lock is a very good *medium security* padlock. It isn't meant to secure your high dollar bicycle on the streets of New York City. It's meant to keep honest people honest.The body of this lock isn't solid steel. It is not going to resist brute force attacks. The shackle is hardened, but isn't thick enough to resist large bolt cutters.So again... MEDIUM SECURITY application lock, which it excels at.I'm into lock sport (picking locks), and this series of lock is a fantastic tool for guys to up their lock picking game. Once you've learned to deal with security pins, buy this lock. It will humble you quickly. It is very likely that you will spend weeks to get your first open on an American 1100 series lock. So yes, this lock has decent pick resistance. Very good for a MEDIUM SECURITY lock. It is full of serrated and serrated spool pins.It is unfortunate that one of the chambers of this lock does not come populated with pins. I'm knocking one star off of the rating, because American (owned by Master Lock) is too cheap to populate all of the chambers with pins. It would likely increase the Bill Of Materials cost by two pennies to add that last pin, but they gotta squeeze every last penny of profit out of things these days.So again, great lock for its intended use. Lock sport guys: buy this lock. Buy a few of them if you can, as they are really *that* good at teaching picking techniques for the pins used in this lock.

These are very good quality locks they hold up well to the elements. They have a few security pins that makes it take longer to pick if you are a beginner. The shackle is fairly hard and cant be cut easily with small bolt cutters. A angle grinder will buzz right through it though.

Durable and strong.
