Night Latches & Rim Locks
Nightlatches come in all shapes and sizes and with various levels of security. They are also commonly referred to as Yale locks, since Yale has a long standing history of manufacturing them. Many of these locks have something known as slam locking which basically means that once you close the door, it will automatically lock itself and can only be opened again with the key. This lock is usually installed onto the surface of a wooden door rather than being morticed into the door frame itself, making for easy and cheap installation. There are a few options when it comes to purchasing Nightlatches, from the most basic Nightlatch which will provide a basic level of protection and can be used together with a mortice lock, to high security British Standard Night Latches that offers maximum security and are insurance and police approved.
