Castles Mettham

When my parents broke an old door lock at the entrance, it became necessary to buy a new lock. I took this whole matter into my own hands and decided to order it on the Internet.

The price and appearance, as well as the most diverse qualities of the castle suited me. The master did the installation of the lock so that everything was reliable. The castle has not served the parents for long, only 3 months, but it justifies all its qualities, it locks easily, not noisily, the cover does not peel off. In general, I am happy with the purchase, and my parents too.

After changing the doors to the entrance to sound ones, metal ones had to be put in a normal lock. The first, with the keys did not hold out and six months after which he was knocked out. For some time the door was without a lock, but the neighbors finally dropped and bought an inexpensive domestic lock Mettem ZKP-2. It costs a little more than the first model, the mater explained that we have a 4 cm door and we need an appropriate mechanism.
The castle has been standing for a year and does not cause any special complaints, during this time I had to change the code twice. The first time they called the wizard, the second time the neighbor changed himself from memory. So often I had to change because the buttons are slightly wiped and you can guess what code is now installed on the lock. It works well even in winter in the cold.

Recently, we had to repair the lock with the mettem standard n. 6 level with an asymmetric (one-sided) arrangement of level. The keys to it were brass with the displacement of the beards in the eyes, which gave good secrecy. In addition, there was a different thickness of the barbs themselves, which gave protection against sticking the key in the wrong direction.

After opening, the lubricant completely dried out and a lot of dirt was found, which is quite expected for a mechanism with such slots in the case and lack of protection on the keyhole. After lubrication and cleaning, the lock began to work again. Only slightly jammed at even speeds. In general, this is a reliable mechanism for protecting the premises that can be operated in extreme conditions, but for those who know something about the mechanics and can disassemble, clean and lubricate it once a year.

Not so long ago, an old fence was turned around in our country house with a car, which accelerated the need to build a new one from a metal profile. The corresponding gate was also made in the fence, into which it was decided to insert a combination lock. The main criterion was its low cost with minimal strength indicators.

On the market, we were advised to buy the ZKP-1 of the domestic manufacturer METTEM, its price was, of course, not the minimum, but the Chinese counterparts looked so flimsy that they decided not to be greedy. Installed themselves and without problems. Very convenient to configure, you can easily change the number and location of active buttons. It is advisable to change them at least once every six months, since the frequently used buttons remain shiny, and not the active ones are covered with a touch of rust, according to this sign, you can calculate the code.

After the lock on the internal entrance door broke in the parents' apartment, I decided to put them in a reliable mechanism with maximum protection against hacking, since the area where they live is not too safe in terms of apartment thefts.
I bought a lock in a specialized store. The criteria that were presented to the products corresponded to many imported models, but their price was simply sky-high. The seller advised the domestic manufacturer METTEMI and his lock series super protection model 3B8 141.0.1. the design of the locks was suitable, in addition, he was the only one examined who had a special design of the crossbar due to which it cannot be opened by “folding”.
The lock was installed by itself, complete with all the necessary fasteners. Operated for six months. The paint does not peel off, it works fine, though it's too noisy.

Relatively inexpensive, reliable, super protection function

There was a need to purchase an inexpensive and easy to maintain combination lock for a new armored entrance door. In the store of combination locks that are not connected to electricity and do not raise doubts about their reliability, only the ZKP-1 model of the domestic manufacturer METTEM was found. As a mechanism, the lock is completely satisfied, but the accompanying drawing and design documentation does not withstand any criticism. There are no main overall and connecting dimensions necessary for quick and correct installation of the lock.

I had to tinker with the installation, re-drilling the mounting holes and hollowing out additional grooves. I can’t say anything bad about operation. During the operation - 1 year there were no complaints.

reliable, solid, high-quality, low cost
