ABS cylinders are the original sacrificial breakpoint cylinders meeting Sold Secure Diamond and TS007 3* standards. The sacrificial breakpoint technology on ABS cylinders ensures the cam remains in place if the cylinder is attacked.
The new ABS Quantum Thumbturn now allows for full compatibility with latch-locking doors. This ensures that no matter what position the thumb turn has been left in when the door has been closed the key will still be able to open the door from the outside.
If ABS is snap-attacked from the outside, sacrificial breakpoint protection is triggered and the cam is locked into position to prevent the door from being opened. To open the door after a lock-snapping attack, the thumb turn is pushed in to rotate and safely open and close the door from the inside.
Please contact Duffells to ensure the British Standard kitemark is retained when keying alike as we are BSI certified to carry out this work.
*Please note: A 30mm size barrel does not have the kitemark stamp as it is physically smaller and does not have the snap sacrificial line.
When choosing a cylinder the size will determine the turn and sacrificial breakpoint sides of the barrel. Example: T35/45S means that the turn is on the 35mm side and the 45mm side has a sacrificial breakpoint.
