Lock case LC301X

The lock can be opened either with a key (outside and inside) or by using an emergency thumbturn (sliding snib in UP position). Latchbolt can be retained inside the lock case (sliding snib in DOWN position). Sliding snib is released only when turning the key. Microswitch version. The switch changes it’s status when the latchbolt is fully extended. The lock case works with the 4613 and 4614 striker plates.
