Yale Polished Brass Night Latch 40mm
Yale Polished Brass Deadlocking Nightlatch provides a high security nightlatch with a rim cylinder and 2 keys. The inside handle can be deadlocked by a reverse turn of the key in the outside cylinder after closing the door. It is deadlocked by the snib button internally which makes the lock inoperable by key or handle. The snib button can also be used to hold back the latch to keep the door open.
