Product description

The sliding window lock allows you to control the opening range of the window. It can be fully closed or only slightly opened for ventilation. This effectively reduces the risk of accidents and ensures their safety.

If you wish to keep the window open to let in fresh air, you can adjust the lock to allow the window to open slightly, or set it to a position that allows the window to open wider. In this case, a sliding window lock is your best solution.

The window lock can be easily adjusted for reuse or reinstallation, allowing for either a full closure or a limited opening for ventilation. Heavy-duty doors and windows can be secured with multiple locks simultaneously to enhance stability and security. (Depending on the space available in the window track, you can use either an Allen wrench or a vertical key to complete the installation.)
