Yale Assa Abloy Traditional Nihtlatch P89

The Traditional Nightlatch P89 is a robust and versatile door locking solution designed to enhance home security while offering convenient functionality. Featuring a 60mm backset, this nightlatch is suitable for both left- and right-handed doors that open inward and are up to 57mm thick. The lock includes a high-security anti-bump cylinder, providing strong protection against common lock tampering techniques. Its classic design ensures it blends seamlessly with traditional and modern doors alike.

For added flexibility, the P89 nightlatch offers multiple security features. The internal handle can be deadlocked by simply reversing the key from the outside once the door is closed, preventing unauthorized access even if the key is later used. Additionally, the built-in snib function allows the latch to be held back when needed, offering temporary free access. When activated, the snib can also deadlock the latch internally, rendering both the handle and key inoperable—ideal for securing the door fully when occupants are inside.
