The Abus 402 D-Lock offers superb protection and security for your bike. It features an 11mm hardened steel shackle and a modern ultra-strong double-locking mechanism to resist thieve’s attempts at stealing your bike. The round handle is made of 11mm specially hardened steel and is double-locked in the lock body. Plus, its lock body and the locking mechanism are constructed using the same high-quality steel as the shackle itself. And, the shackle resists cutting while the double locking mechanism is reinforced against bashing, picking or manipulation.
