With these mortise locks the locked door cannot be opened by handle from the inside, so they are not to be installed in doors on escape routes or panic exit doors.
Apart from the panic function, however, they have all the advantages of their emergency exit counterparts. Thanks to their security, wide functionality, robust design and durability, they can be used in most security doors.

These locks operate in a joint double side or split handle controlled way. Tubular frame and full leaf models are available.
