Night Latches

Nightlatches come in a wide variety of styles and in two sizes with many different capabilities.

If you already have a nightlatch that you wish to replace, then to get the correct size you wouod need to measure horizontally from the edge of the door to the centre of the keyhole of your existing nightlatch.  If this measurement is 44mm then your replacement nightlatch would need to be a ‘narrow’ nightlatch.  If this measurement is 60mm then you would need a ‘standard’ nightlatch.

Of course, if you have a new door without any existing fittings then any of the standard sizes would fit as long as your door stile is wide enough to accommodate this size.

Rim Nightlatches – Non Deadlocking

The main latch bolt in a nightlatch has a rounded leading edge and is spring loaded.  As you turn the inside knob the latch is withdrawn into the casing.  You can close the door by simply pushing the door into its frame.  A key is required to unlock them from the outside.  The latch can be deadlocked in an open or closed position by sliding the snib on the inner face.  A nightlatch should be supplemented by one or two deadlocks.  See our comprehensive range in both narrow and standard sizes in all finishes to complement your interior.  Chrome and nickel look great in modern interiors and brass is warm and more suited to a traditional or classic decor.

Rim Nightlatches – Deadlocking

On this type of nightlatch the latch bolt can also be deadlocked by the key from outside or the key from the inside. The holdback facility can be operated by rotating the handle and depressing the pushbutton and then released by rotating the handle again.  

It is very common to fit a cylinder pull to assist with closing the door and these are available in matching finishes.
