Nightlatch

Discover the UNION Cylinder Nightlatch, a reliable and efficient non-deadlocking solution designed for automatic door security. Ideal for homes and offices, this standard-style nightlatch ensures your door locks securely the moment it closes, offering peace of mind and convenience.

 It is not deadlocking and is therefore ideal for most applications. Using the snib you can either hold the latch in the retracted position to allow free entry or in the locked position to avoid external manipulation. The outside cylinder is used to retract the latch but will not open if the inside snib is deadlocking the lock.
