Chubb Isolater safe 

We don't use TL or UL ratings in the UK we use the European grading system. These isolator mechanisms cone in 7 or more models, the closest you would see in the USA would be the Chatwood Milner Monarch

@@MrKelocks Wow! from what I know a euro grade 5 safe is equivalent to a TRTL 30x6 and a grade 6 is equivalent to a UL rated TRTL60X6 so grade 7 must offer more protection then the highest UL rated stuff.... I could be wrong though, that's just what I gathered from reading online but it's rather difficult to find literature with direct comparisons between U.L ratings and the Euro Grading system.

​@Lgg42069 this was a Bankers Treasury so makes it a Grade 5 with £100000.00 overnight insurance cash cover

As some one in south Africa that dose the same thing here I can appreciate the work, those are 6k18 locks if I'm not wrong. What picks are you using?

@@quintonmoolman7803 what type of security grading system is most common in South Africa? U.L or Euro Grading ?
