Updated 2026-09-05

Designed for versatile security applications, this four foot chain lock is suitable for bicycles, motorcycles, and residential gates. The length provides sufficient flexibility to wrap around large posts or multiple frames simultaneously. It features a high-security disc-style cylinder that is pick and drill resistant, ensuring the locking mechanism remains uncompromised during attempted thefts.

The chain is comprised of 9mm four-sided links crafted from hardened manganese steel, offering a high level of resistance against cutting tools. The integrated lock head features a patent-pending talon deadbolt design that provides extra holding power. This construction eliminates the need for a separate padlock, reducing the number of components the user must manage.

To protect the surfaces of bikes or fences, the chain is encased in a rugged nylon sleeve that prevents metal-on-metal contact. The package includes two ergonomic keys designed to reduce torque and prevent bending or breaking. This model is an excellent choice for those needing reliable protection for property in various outdoor settings.
