Thick Chain Lock with Keyed Backup

$59.99

Catalog updated 2026-10-21

This model enhances traditional security by combining an 8mm thick steel chain with a modern biometric interface. Unlike standard electronic locks, this version includes physical keys as a reliable backup method, ensuring access even if the battery is depleted. The thicker chain links provide increased resistance against bolt cutters and other common theft tools.

The waterproof exterior is designed to withstand the elements, protecting the sensitive fingerprint scanner from moisture and dust. At 3.28 feet long, the chain is perfectly sized for securing bicycles, scooters, and motorcycles to racks or poles. The heavy-duty construction is complemented by a fabric sleeve that keeps the metal links from damaging paintwork.

Security is managed through a combination of biometric data and mechanical hardware, offering peace of mind for high-risk parking areas. The 8mm thickness is a significant upgrade for those prioritizing physical strength in their locking hardware. It is an excellent choice for securing residential gates or commercial fences that require frequent, secure access by multiple users.
