Let's call the client Paul. He installed identical cylinders on two doors. One mechanism on the apartment door worked for many years without any problems. On the outer door, the second one began to jam much earlier.
A question has arisen:
“If the model is the same, why is the service life so different?”
Because the mechanism does not work in the laboratory, but in specific conditions. The materials provided list cylinder wear factors as contamination, daily use, key damage, moisture and corrosion.
Environmental conditions
Inside the entrance, the mechanism may have almost no contact with:
- rain;
- snow;
- salt.
Outside the building the situation is completely different.
Frequency of use
The office door may open dozens of times a day. Utility door - several times a week. The number of operating cycles affects wear.
Door status
If one door is perfectly adjusted and the other has to be pressed down every time, the locks are under different loads.
Key quality
One mechanism can be used with neat original keys. In another, the following are constantly used:
- worn out;
- deformed;
- inaccurate copies.
Why you can't promise a fixed service life
Even a high-quality mechanism can work completely differently in different conditions. Therefore, it is much more useful to track your condition than to focus only on the number of years.
