How to lock the window handle

  To lock the aluminum alloy window handle, the following methods can be used

1. Adjust hinges

  If the window sash cannot be fully closed, it may be due to a problem at the hinges. You can use a Phillips screwdriver to tighten the screws at the upper and lower hinges to ensure that the window sash can be fully closed.

  2.Adjust the handle

 If the problem lies in the window handle being loose, first check the cause of the looseness and then handle it according to the actual situation. If the loosening of the screw fixing the handle is due to prolonged force, use a screwdriver to tighten the screw. If the looseness is caused by insufficient length of the screw that fixes the handle, it is necessary to choose a longer screw and fix it from the outer side of the glass

 3.Adjust hardware 

 For broken bridge aluminum windows, if two small circular holes are found on the top and bottom of the hardware, you can use an Allen wrench tool to rotate it counterclockwise to adjust the tightness of the window until it can be tightly closed and the handle can be placed correctly without difficulty.

 4.Check installation quality

  Ensure that the relevant deviation requirements of the installation process are met during the installation process, and check and adjust the installation quality of each process at any time to ensure that it meets the relevant deviation requirements of the installation

 It can effectively solve the problem of loose aluminum alloy window handles, ensure that windows can be tightly closed, and improve the functionality and safety of window use.
