Loud alarm heavy duty chain lock

Updated 2026-09-05

Measuring 45.5 in long, this heavy duty chain lock offers the flexibility needed to secure motorcycles, scooters, or large gates. The integrated 120db alarm system provides an immediate audible response to any unauthorized movement or tampering. The chain links are encased in a protective sleeve to prevent scratches on your vehicle's finish.

The multi-purpose design makes it suitable for a wide range of applications beyond cycling, including securing garden equipment or perimeter fences. The 120db siren is loud enough to be heard from a significant distance, acting as a powerful deterrent. Its rugged construction is built to survive harsh outdoor environments and physical force.

The keyed locking head is integrated directly with the alarm module, creating a seamless security interface. The 4 feet length provides ample slack for wrapping around thick pillars or multiple bikes at once. This chain lock is an excellent investment for those needing versatile, high-decibel protection for larger assets and outdoor property.
