Snap resistant cylinder locks - pExtra Guard
Snap resistant cylinder locks - pExtra Guard

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.

To effectively protect your door, the Door & Hardware Federation in the UK (DHF) advises that the lock cylinder and door handles on external entrance doors should meet the highest standard, and protect against all the latest forms of attack. The DHF advises home and business owners that their lock cylinders should be upgraded to the TS007 Kitemark standard.

Secured by Design (the Association of Chief Police Officer’s crime prevention initiative) has worked with the DHF and the Glass & Glazing Federation (GGF) to develop the TS007 standard.
