Nightlatches

A nightlatch is mounted onto the door instead of being morticed into it.

The size of nightlatch you require is often dependent on whether or not you are fitting it to a panelled door.

There are many types of nightlatches available. If you are securing an external door, always look for a British Standard nightlatch to ensure a high level of security.

How to measure for your nightlatch

Nightlatches are available in 2 sizes, 40mm and 60mm. The size describes the position of the keyhole from the edge of the door and is important to know if you are replacing a lock or if you are fitting a lock to a door which has a narrow frame.

Measuring the backset
Nightlatches are available in two different sizes - 40mm or 60mm. This measurement is the distance from the keyhole to the edge of the door. If you have a panelled door you will probably need to buy a 40mm nightlatch to make sure that it fits on to the door.

Double locking nightlatches
Double locking nightlatches have a keyhole on the handle inside the door so that the nightlatch can be deadlocked from inside. This is useful if you have a glass panelled door as if a burglar smashes the glass and reaches in, they won't be able to unlock the door.
