1. When the door is at a certain distance from the door frame, it will automatically close slowly; It has a number of patents on damping technology and automatic closing technology, and its service life has reached more than 50,000 times.
2. The anti-jump wheel prevents the light door from jumping open;
3. Automatic traction reset function device after unhooking to avoid failure after damping unhooking (no damping buffering function);
4. The positioner is simple and quick to install, and can be adjusted with one key and multiple functions (it is convenient to adjust and control the height of the anti-jump pedal and the positioner).
I hope my answer can help you.
