A proper workhorse of the UK Safe stock from when we did things properly.
An Isolator service is labour intensive for all the right reasons, unlike many modern day units.
The main issue on this was a Bush had detached and causing intermittent lock outs.
They were very lucky for it not to go full lockout.
When that happens on one of Britain's finest, especially if you get the wrong guy in to make it right, they dig their heels in and things go from bad to worse.
This safe had obviously had water ingress at some point too. It cleaned up well, the detached bushing went back with locktite and some adjustments to the casting to ensure it didn't relapse.
Alignment is important too on reassembly, regularly this isn't done well and the stresses put strain on the scroll.
A well maintained Chubb Isolator will last a lifetime. There used to be several in almost every bank un the UK.
Now the highstreets have been stripped, the remainders are still to be found in quality businesses but the vast majority have now been shipped over seas to the east.
