The KryptoLok Series 2 STD U-lock is like a tough nut: you just can't crack it. Thanks to the 13mm hardened Performance 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 lock includes two “I” keys for the disc-style cylinder--one of which features an LED light--not to mention the Transit Flex Frame bracket for plenty of convenient mounting options. The KryptoLok series 2 STD is 4 x 9-inches and has an anti-theft protection offer.
Kryptonite's Key Safe Program is an easy way to ensure you always have access to your lock's capabilities. Simply register your key number with Kryptonite and if you lose your keys, your first set of replacement keys are free!
