## Long description

The MASTER LOCK 8391EURDPRO chain lock is a steel security solution designed for securing bicycles, gates and other outdoor valuables. The chain measures 900 mm in length and 8 mm in diameter, and it features a protective black finish that helps resist corrosion and reduces wear to painted surfaces. Its compact proportions and robust steel construction deliver a balance of portability and theft deterrence for everyday use.
Advantages
The steel chain construction provides mechanical strength appropriate for deterring opportunistic theft. The 8 mm diameter links combine resistance with manageable weight, while the 900 mm length offers flexibility for locking bikes to a variety of fixed objects. The black protective coating helps prevent rust and minimizes contact damage to frames and other surfaces. The design is straightforward and easy to operate without specialized tools.

Key specifications
 Material: steel chain with protective coating
 Length: 900 mm
 Link diameter: 8 mm
 Finish: black protective coating
 Typical use: outdoor and transport security for bicycles and similar items
How to use
Wrap the chain around the frame or a solid frame component of the bicycle and through a fixed object such as a rack or post. Ensure the chain passes through the wheel if required for additional security, then secure the chain with the lock mechanism supplied. Position the lock and chain so that access to the locking mechanism is obstructed and the chain rests snugly to reduce leverage points. Store the chain in a dry place when not in use to prolong the life of the protective coating.
Usage recommendations
For improved security, use the chain lock in combination with a secondary locking device (for example a U-lock or cable) and attach to well-lit, busy areas. Regularly inspect the chain and coating for signs of wear or corrosion and clean with a mild detergent and dry thoroughly before storage. Avoid exposing the lock to prolonged saltwater conditions without rinsing to prevent accelerated corrosion.
