Abus Adaptor Chain ACH 6KS

It doesn't get any easier than this - 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 especially simple to double the security of your bike: just wrap 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 won't need an additional key, nor do you have to lock the shackle separately. The Chain Frame Lock Chain is compatible with Abus Frame Locks 4960, 5850, 5650, and 5950.
