## Long description

The MASTERLOCK QUANTUM 8392 chain-style bike lock combines a compact, flexible design with an integrated combination locking mechanism. The chain is 8 mm thick and 90 cm long, allowing it to secure a bicycle frame or scooter to a fixed object. Supplied as a boxed assortment of six pieces in mixed colors, this lock is intended for everyday theft deterrence and short-term unattended parking of personal transport devices.
Advantages
The lock's 8 mm hardened chain links provide a balance of flexibility and resistance to casual cutting attempts while the integrated combination mechanism removes the need for a key. With a 90 cm length the chain wraps around frames and poles with practical ease, and the assortment packaging supports bulk distribution or retail display. The compact, keyless design is convenient for daily use and requires minimal maintenance.
Suitable for
 Securing children's bicycles and scooters

Key specifications
 Chain thickness: 8 mm
 Chain length: 90 cm
 Lock type: integrated combination mechanism (keyless)
 Finish: assorted mixed colors
 Packaging: boxed set of six pieces
How to use
To secure a bicycle or scooter, wrap the chain around the frame and a fixed object such as a rack or pole, then align the chain ends and set the combination to lock. Ensure the chain passes through or around the frame and a wheel where possible to reduce leverage attacks. Store the combination in a secure place or memorise it to avoid accidental lockouts. Periodically inspect the chain and locking mechanism for wear, dirt or corrosion and clean and lubricate the combination components if movement becomes stiff.
Usage recommendations
For improved theft deterrence, use the chain lock in combination with a second lock or secure both the frame and at least one wheel. Avoid leaving the bike in isolated or poorly lit areas for extended periods and choose fixed anchoring points that cannot be easily removed.
