Weighing in at just 536 grams and available in four painted and two anodized metallic finishes, the XZ1 is a light, stylish and portable alarmed lock that’s easy on the budget. All XZ Series locks feature a 6mm steel locking pin for a broad fit profile, pushdown locking mechanism and XENA’s patented 110dB alarm linked to shock and motion sensors. The XZ’s lock body dimensions are identical to its slightly stronger cousin, the XR Series. Where they differ is module configuration: with the XZ, the outer casing of the removable alarm module completes the structure of the back of the lock. The XR’s module is covered by a removable steel lid.
