Hey IDN, how can I tell the difference between Schlage’s ND Lock from previous years & their new ND lock released in 2017.


Yes, the lock has been redesigned for 2017 and many parts are no longer interchangeable. Have a look at this handy chart from Allegion. It has the visual clues you need and a list of many new components.
