Master Lock 410GRN Lockout Tagout Safety Padlock with Key Green 0.25 in. Shackle Diameter

Its a nice sturdy lock.

For its intended purpose - safety lockout - it's pretty good. It's not coming off the machine it's locking without a key or destroying it. For hobby lockpickers like me it's great because it's got the best core Master makes. Ok, that's not saying much, but seriously the 6-pin core on this thing is actually pretty good despite having been made by Master. This lock is harder to pick than an American 1100. Which, really, begs the question why their best core can only be found in a plastic lock when they've got locks that are invulnerable to any destructive attack short of power tools that can be picked by a 10 year old. But still, I think this lock is an essential addition to any intermediate hobby lockpicker's collection.

First of all, never pick a lock you don't own, and never pick a lock that is in regular use. These rules especially apply for these locks! If you're getting into picking locks and looking for something with a few security pins on the cheap, these are the most secure cores Master Lock makes. Just don't turn the core past where it would normally go in operation, there's nothing retaining the pins and you'll get a very fancy rattle.

Saved me from work I lost mine, but thankfully right after I got them they started writing down the serial numbers on them cause ig people did same thing as me

Good core which can be dropped into an American a1100 after you over rotate it and dump the pins inside the lock body and have to break the case and put the pins back in the core. But it wasn't designed for picking so no points off on there. A bit rough, and a bit of a challenge to pick.

I bought this lock to practice lock picking. It was a great challenge to get into with its tiny spool and serrated pins. My brother is a truck driver and uses these on shipments that don't come with a seal. They're great for that purpose since they can't be shimmed open (ball bearing design) and are a bit of a challenge to pick. Of course, they can just be smashed open since the body is made of plastic, but that would leave a mark and let him know to report it.

It is strange to see such good pick resistance from master lock, especially in a low security plastic body lock. The pins will wear down after extended use (of practice), but that is normal. This has some deep spools and I had a lot of fun picking it open.

Works well

That is a good lock for personnal security use at work and to lock machines or electrical panels...for our own security.

Good safety padlock. Standard with unique key. It also comes with the stickers in several languages English/Spanish...
