The CHAIN Frame Lock Chain from ABUS makes it particularly easy to make your bicycle twice as secure: simply place the chain around a fixed object, pull the end with the lock through the ring on the chain and attach it to the lock housing. You will not need another key, nor will you need to lock the shackle separately. The adapter chain can be inserted into all ABUS frame locks whose product names contain a combination of four numbers.

• 6 mm thick, square chain made of hardened steel
• Separate locking of the shackle is not necessary
• Opens up a lot of opportunities for locking the bicycle on to a fixed object
• Suitable for use with frame locks 4960, 5850, 5650, 5750 and 5950
