security cylinder lock
Pextra Guard break secure lock has been developed specifically to meet the TS007 3-Star standard for lock cylinders and has undergone rigorous testing prior to its full approval to the new standard. Many customers refer to anti snap, snap resistant cylinders which is an inaccurate term as the cylinder has been designed to snap but in a secure/ safe manner to ensure even after snapping the cylinder can't be manipulated or overcome even with tools.
To provide a counter measure to, amongst others, the increasing threat of snapping locks, the cylinder itself features several layers of protection. In particular, the cylinder features a sacrificial break slot, which ensures that in the event of the cylinder being snapped, the secure core of the lock is retained within the door preventing forced override of the cylinder.
