Yale P85 Deadlocking Nightlatch 40mm Backset - Brasslux Finish
Secure Yale P85 deadlocking nightlatch (40mm backset) with auto-deadlock, snib function & Brasslux finish.
The Yale P85 Deadlocking Nightlatch is a high-security front door latch designed for reliability and ease of use. Part of Yale's widely trusted 85 series, this nightlatch is operated by key from the outside and a lever handle from the inside. Its auto-deadlocking mechanism ensures enhanced security the moment the door is closed, while the convenient snib (bolt hold-back button) allows the latch to be held in an open position. With a reverse turn of the key, the inside handle can also be deadlocked—preventing the door from being opened from the inside without the key.
This model includes a 1109 cylinder for secure key operation and comes in a durable Brasslux finish, combining both elegance and robustness. The 40mm backset (measured from the door edge to the centre of the keyhole) makes it ideal for doors with restricted space, such as narrow glass-panelled doors. The hardened case finish and polished brass cylinder further enhance durability and security. Backed by a 2-year guarantee, this nightlatch meets high-security standards and provides dependable protection for your home.
