brightonkeys Posted July 6, 2017 Report Share Posted July 6, 2017 What is the difference between a 'differ' and a 'submaster' when it comes to designing a suite of locks for, say, a school? Is one advantageous to the other? Is one riskier than the other if a key was lost? I thought I understood all this until someone at the wholesaler rocked the boat! I'm glad they did because it looks like I don't know what I thought I did... Quote Link to comment Share on other sites More sharing options...
grahamparker Posted July 6, 2017 Report Share Posted July 6, 2017 Master suites usually follow this pattern. Differ Sub master Master Grand master Great grand master. You need to break them down. It's like a family tree you start with the master at the top Then you can have say sub suites a,b,c which have differs 1-4 So master fits all Sub master a fits all in group a (same for b and c) Differ a1 fits a1 only. Next differ is a2 and so on. Quote Link to comment Share on other sites More sharing options...

brightonkeys Posted July 6, 2017 Author Report Share Posted July 6, 2017 like this Drat. That's what I thought. The wholesaler was talking about something else. About a risk where if a differ key was lost all the cylinders would have to be changed but whereas if a submaster was lost that would not be the case. Think I'll need to give him a ring...

Mick Friend Posted July 6, 2017 Report Share Posted July 6, 2017 yes the higher the tree the more of a problem it is but a single room key no worries a section key on the lower level just change the rooms on that level - most cylinders could then be re-pinned to another sub master key kobblers 1 Quote Link to comment Share on other sites More sharing options...
