A window lock and a window handle serve different functions in window operation and security. Window Lock: This internal locking mechanism secures the window in place, preventing it from being opened without a key or lever. It enhances safety by deterring unauthorised access. Window Handle: This is the part used to open and close the window. It allows users to easily operate the window and may also incorporate a locking mechanism for added security. In summary, the window lock focuses on security, while the window handle facilitates the window’s operation.
