Новый замок для калиток Полис 18

In Saratov, electromechanical locks have been made for many years. The design of the lock changes greatly over time. And almost always for the better. In this video, I examined the design of the lock as closely as possible. I tried to explain how this lock works and delve into the design features. I assembled a test stand for the lock. And tested the operation of the lock at different distances between the frame and the door. In general, I conducted full tests of the lock.
