What is a Cylinder Nightlatch

Cheap cylinder night hatches are often regarded as offering poor security. More expensive versions offer more security but make sure they have accreditation from the various standards authorities.

The problem with the standard nightlatch is that a burglar can break the glass in a door, reach round and undo the latch. You can take the precaution of installing a deadlocking cylinder latch. When you turn the key as you leave the house, the lock becomes set.
To lock while your indoors, choose a model with knob locking so that it can be locked from indoors as well as outdoors. For fire and safety reasons, ensure that a key is kept near the door.
