Problem 1. What should I do if I encounter the phenomenon that doors and windows cannot be closed and the air leaks and fills the wind?
Solution: 1 . Open Broken Bridge aluminum Casement.
2 . We will see two small round holes up and down the broken bridge aluminum hardware.
When we see that there are two small round holes up and down the broken bridge aluminum Casement, we can use the Allen wrench tool to rotate it counterclockwise. At this time, we will close the window and try the tightness. If it is still loose, then rotate again until the window is closed strictly and it is not difficult to put your hands right.
