From Yale Locks, the 706 Traditional Nightlatch is a classic-style Nightlatch designed for key operation from the outside, with a knob handle for use from inside. A deadlocking snib function allows the latch to be held back when required, or deadlocked internally for added control over access. With a 40mm backset (measured from the edge of the door to the centre of the keyhole), this Nightlatch is suited to doors where space is restricted, such as narrow glass panelled doors. It is finished in electro nickle brass on the case, paired with a polished brass cylinder finish, for a traditional look that complements a range of door styles.
