Master LockA1107BLU Aluminum Blue Safety Padlock with 1/4" x 3" Shackle (Pack of 6)

This is an American lock...that's all you need to know.I bought the longer shackle to fit my Yeti65, Grizly100 and Kodi Roadie coolers to lock them shut, it fits all of them.I pulled the core and re-pinned to 6pins like all the others I have.

Fites ezloader boat trailer coupling.

Amazing lock to start to learn locksporting... Nice lock to start learning what serrated and spooled pins feel like and what happens when you in a false set and start to get counter rotation... great lock for a cheap price...

I got a 2.5 inch red one as a gift for my storage trunk years ago and still have it. Got a second trunk and wanted another because it was such a good lock. Needed one longer than 2.5 inches and saw this.. and in blue!? purchased on the spot.

Para la seguridad y facil para usar me resulto excelente

I bought this to practice learning to pick serrated pins with. I'm a locksmith, so it is important that I can pick all kinds of locks with different varying levels of difficulty. This lock put up a fight, but it taught me a great deal, so I am very happy with my purchase

Good construction. I use these at food processing plants in harsh chemical areas. They seem to stand up well.

I used it for work and I like it

Nice lock
