ERA Nightlatch Deadlock — 40mm Backset, Grey

The ERA Nightlatch Deadlock (DF184) provides additional security to replace most existing front door locks. Automatic deadlocking prevents the bolt from being retracted by a credit card — a critical security advantage that makes forced entry significantly harder.

The ergonomic internal locking handle can be deadlocked by an anti-clockwise turn of the key from the inside, offering additional protection against forced entry through glass panelled doors. A simple snib button holds the latch withdrawn for easy access without operating the handle.

Face-fitted and non-handed, it suits both left and right-hand inward opening timber doors. The striker features a 3-hole fixing for added strength. The rim cylinder is supplied with 3 cut keys and can be keyed to pass or master keyed.
