Kryptonite’s Keeper 12 U-Lock is like a tough nut: you just can’t crack it. Thanks to the 12mm hardened steel shackle that resists cutting and leverage attacks, you get peace-of-mind while you run into the grocery store or lock up outside the coffee shop. The shackle connects to the disc-style cylinder for exceptional security, and it all sits in the click-style transportation bracket so it stays stable during transport. To top it all off, you get a reinforced collar over the keyway for added protection.
