There is no need to define the word “castle”. And this is the advantage of locks – everyone, from the mayor to the ordinary housewife, knows what locks are for doors. However, not everyone knows how castles differ from each other? What are the advantages of one type of lock over another? Guided by design or intuitive considerations when choosing this simple mechanism? And then the unexpected happens: at least – the inability to enter the premises due to a suddenly slammed door, or even a burglary.
The degree of reliability of the lock.
The most important criterion when choosing a door lock, paradoxical as it sounds, is the time it takes to crack it..
According to the degree of their reliability, all locks are divided into 4 categories. The first 2 categories are locks, which require a few minutes to open without the original key. They are suitable only for interior doors or interior spaces in offices. Locks of the 3rd category have increased locking properties and it is almost impossible to open them without a key in less than 10 minutes. You can learn about opening cylinder locks from specialists when buying them in a store. High locking properties are provided only by the 4th category of locks, breaking which even a professional will spend at least half an hour of his time. In addition, they are able to withstand pressures of more than 1,000 kg..
Confirmation of the reliability of the lock is only the presence of its certificate of conformity.
Lock installation method.
According to the method of installation, locks are mortise, overhead and padlocks. Hinged are most often used in garage doors, cottages and cellars. The burglar will not need to fiddle for a long time, because the padlock is very easy to break with the help of simple improvised means, so apartments are not locked on them. Rim locks are more commonly used on wooden doors. They are equipped with an additional tongue-latch. This will keep the door closed even if the door lock is open. On the inside of such a mechanism is usually a swivel wheel, which is usually used in conjunction with a retractable latch. Finally, mortise locks are the most reliable and popular locks. The door leaf in which they are located serves both as a fastener and at the same time as protection. Mortise locks are considered ideal for steel doors. They are completely invisible and almost do not change the appearance of the doors..
When choosing a door lock, you should also consider the material of the doors. For doors made of different materials, different types of locks are preferred. For security doors, it is recommended to use 2 locks of different types.
