The mortise locks are a special type of locks used in the commercialsecurity industry that require heavy-duty and high-frequency lockapplications. One of the advantages of the European mortise lock is that the mortise lock is produced, the lock cylinder and the drive member (door handle) are produced by different manufacturers, but the specifications are uniform and match each other to produce different functions, which is also the European mortise lock. The door must be equipped with reasonable door hardware to play its greatest role,so he choice of tenon lock should bebased on the choice of the root door type and the actual situation.
