A nightlatch is a type of spring lock that can be opened from the inside by turning a knob, but when opened from the outside it can only be opened using a key.

Here is a list of some of the night latches that Alexandra Locksmith supply.

ERA BS3621 High Security Nightlatch

The BS High Security Nightlatch comes with a 20mm bolt thrower, for extra strength and greater security. It also features an integral cylinder pull which protects the cylinder from being drilled.

This Nightlatch has been designed with an ergonomic internal lockable handle offering added security against forced entry which makes it ideally suited for glass panelled wooden doors.

The ERA High Security Nightlatch meets the tough criteria laid down by insurance companies and the police.

Chubb 4L67E rim lock

The Chubb 4L67E’s hardened steel 20mm deadbolt automatically deadlocks on closing the door, providing convenience with high security.

High security features in the design include drill, saw, pick and torque resistance and an internal lockable handle. This makes the 20mm Chubb rim lock ideal for all types of front doors in particular glazed doors, as the lockable handle cannot be operated through a smashed window.

This nightlatch is highly recommended by insurance companies and the police. It automatically deadlocks when the door is closed. Entry can always be gained by key from outside whether the inside handle is locked or unlocked.

It has a width of 89mm and a body height of 90mm. There is a security pull provided that must be fitted to the door.

This product is especially suitable for glass panel doors.
