​AD Lock 3525-1 Left Lockable Fast 731123

Description

The Swedish-made AD 3525-1 lock, designed for left-hinged doors, provides an exceptionally high level of security and durability for various types of buildings and spaces. This robust lock is crafted from premium Swedish steel that has undergone a meticulous treatment process—including galvanizing, chromating, and epoxy coating—to ensure outstanding rust protection and a long service life, even in demanding environments. The lock is equipped with an extra-strong compression spring that maintains consistent tension over time, ensuring stable and reliable performance during daily use. Its long throw, combined with a high-strength steel bolt, makes the mechanism extremely difficult to force open and highly resistant to break-in attempts. Furthermore, the product is compatible with standard market-available lock cylinders (such as the 1207 cylinder), facilitating seamless integration with existing locking systems. Included with the product are a practical drilling template and clear instructions to simplify installation on doors up to 80 mm thick.
