Important Info Before You Buy
For use on inward opening doors only
Night latch can be dead-locked (double locked) This is done from the INSIDE by a full turn of the key
Double locks from inside, so if some one were to break the glass in a front door or a near by window they can't unlock the night latch with out the use of the key
Latchbolt is withdrawn by handle from inside and by turn of key from outside.
Bolt can be held back by pushing the button on lock case, then released by turning the handle up or down
The main lock bolt “automatically” deadlocks, when the door is closed this makes the use of a credit card to force entry virtually impossible
Comes with three keys
