Kryptonite Keeper 712 Chain Lock Ø7mm 120cm - Black

The 'integrated chains' by Kryptonite eliminates critical vulnerability,
as the end link design secures the chain to the hardened deadbolt.
This additionally increases the security the 7 mm four-sided chain links made from 3T manganese steel offer.
In the combo version, your Keeper 790/712 Integrated Chain is combined with a very robust combination lock,
with an individually adjustable 4-digit code.
