Kryptonite Evolution Series 4 1090 Integrated Chain Lock

The Kryptonite Evolution Series 4 1090 chain lock is a truly exceptional mid-range security system for moderate to high crime areas. Each hardened triple heat-treated boron manganese steel chain is 10mm thick and six sided - you won't find better at this price point. Nylon webbing is a great feature on the Evolution Series 4 as it protects your paint work from getting scratched and helps make portability easier. The chain lock comes with 3 steel keys, one of which is a lighted LED key - making night time locking much easier.

Key Features:

• The hardened triple heat-treated boron manganese steel chains include 10mm six-sided links.
• The integrated chains secure with a new patent-pending integrated Evolution series 4 lock head.
• This innovative series of chains also feature a patent-pending pin-less design which secures the chain to a hardened deadbolt and allows for no weak leak in the chain due to extensive holding power of the link itself against attacks
• Chains are enclosed in a nylon-webbing sleeve to protect paint from scratches and allow for easy portability and tight coiling during storage
• Comes with 3 stainless steel keys including a lighted LED key with replaceable battery and 2 new, ergonomic ’I’ keys
• One key is lighted for easy access at night; replaceable battery insures that light can be used as long as the lock.
• The new ’I’ keys make opening a disc-style cylinder much smoother
