BRINKS - 40mm Solid Brass Keyed Padlock with 2.5” Shackle Clearance, (171-42001)

Nice shacle clerance

This lock does exactly what I need it to do. It secures my valuables discreetly. I didn't think I needed big, obnoxious lock to secure my items. I did however want to know that I was guaranteed that my personal items would be safe when I walked away from them. This lock is discreet and effective. It's pleasing to the eye and it's a deterrent at the same time. It comes with a spare key and the lock does exactly what I need it to do.

I am just getting into lock picking, and this is quickly becoming one of my favorite locks to pick. This really was key to helping me understand spool pins. The spools are cut deep which give you convincing false sets, and lots of counter rotation. There is also plenty of room in the keyway for bottom of the keyway tension. The longer shackle is also a plus as it is easier to hold. I think an experienced lockpicker would be able to figure this out in 30 seconds. Also my binding order was not 1234 like one of the other reviews here it is more like 4132, which is definitely more challenging.

Decent lock. Nice for thicker chains.

Didn't get a chance to use it but this lock fit the dimensions needed for an abf U pack trailer bulkhead which requires a long yet skinny lock.

This fits perfect on an attwood style coupler with the drop-over shackle. I own 2 of these and have used one for years. Just a squirt of lithium grease once a year into the key mechanism.

Easy to use. Keeps my boat safe

We bought this lock in January, and started to use it in March. The lock was only used in warm weather, where it does not snow or rain, and no extreme temperatures. Have only locked and unlocked it several times and unfortunately, today it completely broke. As you can see from the pictures, this is clearly poorly made, not worth the money and the performance is marginal at best. Glad it wasn’t locking anything valuable. Do yourself a favor and spend the few extra dollars to purchase something that is more durable and well made. This will save you issues in the future and certainly protect what you need it for.

I bought this padlock to experiment with lockpicking. Pops open with only moderate effort by a novice picker. Easy to shim as well. At least it's physically robust.

I have recently started lockpicking as a hobby and this lock was open within seconds. I am not good at lockpicking, I essentially just picked around in there and it springs open with ease. If you want this lock to protect any of your things, get a better one.
