Overall Width: 65mm Body Thickness: 31.8mm Shackle Diameter: 12.7mm Vertical Shackle Clearance: 29mm Horizontal Shackle Clearance: 29.5mm 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.
