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 ABS Ultimate Locking 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.

Document Q is a government outline of the legal security standards for doors and windows to resist physical attack by a burglar. This includes the requirements of inherent structural integrity and appropriate hardware performance.
