Description
The Yale 40mm dark grey deadlocking nightlatch is suitable for inward opening, right and left handed doors of a 32-57mm thickness.
Deadlocking from the inside functions by the simple slide of the snib, preventing unlocking by the handle or a key, while reverse turning of the key on the outside prevents unlocking by the inside handle. The inside snib can also be used to hold back the latch, temporarily preventing the door from automatically locking.
