Adding the CHAIN Frame Lock Chain to your ABUS frame lock is a very quick and easy way to double your protection against theft.

It couldn’t be simpler – with this frame lock chain made of hardened steel, you have the perfect secondary security for your bicycle.

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 CHAIN Frame Lock Chain is suitable for use with ABUS frame locks 4960, 5850, 5650, and 5950.
