The SQUIRE SS100 Stronghold Closed Shackle Dual Cylinder Padlock is purpose-designed for extreme resistance against the threat of a sustained attack. This seriously heavy duty padlock is constructed of a solid hardened steel lock body, which is capable of a tensile pull of over 24 tonnes, and a hardened boron steel shackle. Uniquely, the Stronghold® range features an electrophoretic finish for excellent corrosion resistance and can withstand even the harshest environments.

The padlock comes complete with 4 keys, with the option of having the dual cylinder keyed alike to the same key (all 4 keys suit both cylinders) or dual cylinders keyed to differ on different keys (with 2 keys to suit each of the dual cylinders).

CEN means Central European Norm. It was devised some time ago when the major padlock manufacturers got together to devise a testing standard. Until then it was confusing since there were plenty of standards for door locks and safes but non for padlocks. Some insurance companies tired to use these standards in relation to padlocks but it simply didn’t work. Still today you may get asked for a specification that simply can’t relate to a padlock and only to a safe or door lock.

There are 6 levels within the grade ranging from general use to maximum security. CEN Level 6 padlocks are rare and for more commercial and consumer purposes 5 is the highest. We tend to recommend anything between 3-5 for high security applications.

  • GRADE 6 – Maximum Security
  • GRADE 5 – Extra High Security
  • GRADE 4 – High Security
  • GRADE 3 – Medium / High Security
  • GRADE 2 – Standard Security
  • GRADE 1 – Low Security

The grading system is slightly flawed in that a lock only needs to fail one of the minimum criteria to a single category to be reduced to its lowest scoring grade. This means that some padlocks may perform like a CEN 6 padlock in all tests but fail at minus 40 degree centigrade. It would therefore be lowered accordingly.
