A good castle even a wooden entrance door can make a serious obstacle to uninvited guests. The main thing is not to be mistaken in the choice.
Almost any door, with rare exception, needs a castle. Sometimes enough latches with a retainer, but still more often requires something more solid.
By the method of fastening, the locks can be divided into three main types. The first-adventure-well-known castles with a handicraft that hang on the ears of the doors is likely to be the sole purpose of saying that no one is at home. The next visitor is already more serious. Inacontal, the most solid-cutting. According to the selection of the secret mechanism, the locks are divided into suvalid and cylinders. Since this material is devoted to castles for the entrance door to the city apartment, we will consider only mortise locks. Immediately it is possible to make a reservation that there are no locks without flaws, and what is less, the castle is more expensive. Different disadvantages are characteristic of the Suwald and cylinder models, so specialists recommend to put locks of different types on the entrance door.
Suwald locks appeared much earlier cylinder. Their mechanism is based on combinations of spring-loaded plates. For such locks, the key is characterized, which we have been called "Safes". The main disadvantages of the Suwald locks are the possibility of opening them to the brand and the manufacture of the key in the cast. And not only from the original key, but also from the castle itself.
There are suitable locks both domestic and imported castles. They differ in difficulty, the place of installation and the type of door, on which the number of parties of locking, material and the number of deposits (riggers) are calculated. The price of the most simple models of the Suwald locks is $ 12-17. But even in these models, the number of mechanical code combinations at least 1000000. Included, domestic mortise locks with a one-sided locking system "Carat", "Classic", "Garant" can be brought. They have a flat rigle from hardened steel. Interesting enhancement of hooks-abstractions, nominated from a flat brigade when locking and preventing the possibility of pressing the castle with a lever. More expensive models of locks are usually used not one boss, but 3-5 riggers from high-strength steel. Thus, they are almost impossible to press and repel. Well, the most complex models of flowing suvalid locks with a trilateral locking system. In addition to 3-5 bollards, nominated when locking the castle from the door of the door, one more rigle is extended from above and below the door. The door is locked on such a lock turns out to be rigidly fixed in the opening. You can also find such locks as domestic production (for example, "competitor", "standard") at a price of $ 25-50 and imported. The cost of a reliable imported Suwald Castle with a trilateral locking system is $ 75-100.
Much more distribution now have cylinder locks, more famous for us called "English". Compared to Suwald, they have a certain advantage. Since they have a hole for the key much already, make the key's key directly from the lock much more difficult, as to choose a wash. But also from cylinder locks, especially inexpensive, there are several flaws that need to be remembered.
The cylinder locks, in contrast to the suvalid, are extremely sensitive to falling into the keyhole of foreign objects and dirt. In addition, the cylinder lock can be knocked out by a heavy item, since as a result of the mechanism, the locking screw is broken down by the mechanism. Well, the most common way of hacking is the drill of the coded mechanism drill. It does not even need an electric drill, quite ordinary mechanical. After the code mechanism is drilled, the lock opens if not with a finger, then any screwdriver. And finally, you should not discount the possibility of pressing the lever unoccupied by the doors.
With many of these shortcomings learned to fight. So, from the removal of the cast from the lock and knock out the special bron alphabets protect. The code mechanisms of high-level cylinder locks are characterized by such a high difficulty that the duplicates of the keys can be made only at the factory. AV quality protection against drilling in good locks is provided with pressed inserts from alloy steel, leading the drill to the side of the mechanism. But all this is characteristic of fairly expensive castles. Auto stores and construction fairs can now meet Russian and Belarusian cylinder locks worth from $ 7 and Turkish from $ 13-15. If you need an inexpensive castle for not very responsible locking, then the only thing that is immediately worth paying attention is the material from which the Rigel is made. If you are offered a lock with a bolt from an unkilled steel or something else softer, it is better to look for a castle just more expensive, but with a riglee from a normal material. If the lock is needed at the front door, it is not worth saving. Now the cylinder lock can be chosen for every taste and almost at any price. It is better to give preference to better, imported cylinder locks. QFV and CES (Germany), ISEO (Italy), Assa (Sweden) are present in the Russian market of KFV and CES (Germany).
In conclusion, several examples of fairly expensive high-class cylinder locks. CISA (Italy) manufactures both sublord and cylinder locks with a trilateral locking system. Cylinder locks are characterized by protection of the cylinder mechanism for armored lining and double mechanical code, which is set by traditional teeth and special wells made by laser technology. The accuracy of the key manufacturing is so high that it can be duplicated only at the factory. The price of such a lock is approximately $ 110.
Extremely reliable locks with a four-sided locking system produces Superlock (Israel). Their price is from $ 120.
A very interesting code mechanism developed ABLOY (Finland). Valid dreams from a conventional cylinder lock, the code in it is set by rotating washers. Such locks are resistant to dust and moisture, have a very high degree of protection, the number of combinations of 360mallions. The cost of the cylinder mechanism from $ 45 to $ 170.
A good castle even a wooden door can make a serious obstacle to uninvited guests. You just need to make a choice correctly.
