Kenstan is proud to introduce a new line of our Keymatic (K) series locks, the K2. In addition to all the features of the original Keymatic series of locks, it has three new features that will help extend the life, ease operation, and simplify installation of the lock. The lock face and the corresponding tubular key have been redesigned by adding an interlocking feature. This interlocking feature creates a solid connection between the key and the lock. Hence, the inserted key can be used as a Pull without damaging the key or the lock.
