## Long description

Chain lock burg wächter SKM 6/ 90 is a 900 mm security chain in black with hardened steel construction and 28×28 mm square links. Its textile coating protects the metal against scratches and weather, while the hardened link profile increases resistance to cutting and levering. The combination of a robust chain design and a compatible padlock or integrated locking mechanism makes this chain suitable for securing bicycles, scooters and other portable equipment in daily urban use.
Advantages
The hardened steel square links and 28×28 mm link dimensions provide elevated shear and cutting resistance compared with thin round-link alternatives. A protective textile sleeve prevents paint damage to frames and reduces corrosion exposure. At 900 mm length the chain offers flexible anchoring options to fixed objects while remaining compact enough for commuting. The product’s construction balances portability and security for routine outdoor use.
Suitable for
Securing bicycles in urban and commuting environments
Locking scooters and e-bikes to fixed fixtures
Temporarily securing portable equipment such as toolboxes or folding trailers
Use where a flexible, weather-protected chain is preferred over rigid locks
Key specifications
Chain length: 900 mm
Link shape: square
Link dimensions: 28 × 28 mm
Material: hardened steel
Protective coating: textile sleeve (black)
Thickness class: hardened chain suitable for everyday outdoor security
How to use
Pass the chain through the frame and both wheels where possible, then loop it around a solid, immovable object such as a bike rack or fixed post. Use a compatible lock with a shackle diameter suitable for square chains or an integrated locking device designed for the chain cross-section. Ensure the chain is pulled snugly to minimize leverage points and avoid leaving excessive slack that could aid cutting tools.
Usage recommendations
For best protection, combine the chain with a high-quality lock rated for outdoor use and position the chain so that the lock mechanism faces downwards and is difficult to access. Store the chain dry when not in use to prolong the textile coating and inspect links regularly for damage. Choose 900 mm length for greater flexibility when securing to larger or irregular anchor points.
