Kitemarked to BS 3621 2007

A deadlocking nightlatch and rim cylinder.

Please remember to check the “backset” size when ordering. This is the distance from the edge of the door to the centre of the cylinder.

This nightlatch can be locked from inside using a key, but can still be opened from outside when the key is used. This nightlatch also comes with an anti-drill plate to cover the rim cylinder and an anti-slip latch. This deadlocks the main latch when the door is closed, preventing force/slip attacks on it.

Deadlocks automatically when the door is closed.

Key operation from outside, with a key and lever handle inside.

Brasslux Case – Brass Cylinder

Chrome Case – Chrome Cylinder
