ATK 3 Star Cylinder Lock Features

  • Patented Snap Secure Technology

    Snapping the lock is a popular method that burglars use to gain entry into your property, with the profile euro cylinder failing to provide the strength or design to prevent it. In response to this, the ATK 3 Star Diamond Cylinder has patented snap secure technology to stand up to attack.

    This is made possible by a multi-part cylinder that responds to a lock snapping attempt by creating a high security barrier to the inner locking mechanism. This prevents a would-be intruder from snapping the cylinder and gaining access.

    These adjustments to the inner workings of the lock allows it to offer complete protection for your home. You’ll be able to relax in the knowledge that your are investing in a new addition to your home that will keep you safe and sound.
