It has been proven that a burglar can gain entry to your property in as little as 13 seconds.

To combat this Avocet has created the 3 Star, British Kitemarked, anti-snap ABS euro cylinder.

This is the ABS Quantum Thumbturn. It operates like a traditional thumbturn and does not require 'clicking' into place as the previous version did

ABS is a retrofit product which means you can simply remove your old lock and replace it with ABS

  • Not supplied with keys - lock only
  • Measurements are taken to the centre screw on this lock
  • Snap Secure Technology - Cam locks against the internal locked side of the cylinder making the cylinder impervious to manual attack after snapping
  • ANTI-SNAP, ANTI-DRILL, ANTI-PICK, ANTI-DRILL
  • TS007 3 star rating
  • Insurance recommended British Kitemark™ stamp
  • Master Locksmith Association's Sold Secure Diamond standard

Please Note: 30mm cylinders do not display a kitemark due to reduced numbers of key combinations. 30mm cylinders do still snap off at the sacrificial point in front of the cam , this ensures an intruder cannot gain access into the lock case.
