Secure Center
Additional security for double-leaf windows made of aluminum, wood, or plastic with a central mullion. Regardless of whether they are made of aluminum, wood, or plastic, your double-leaf windows should always be secured against break-ins. This additional security reliably fulfills this task, even in narrow installation conditions. The solid swivel bolt of the additional security locks automatically, and a key is only needed for opening. The security device is mounted directly on the frame, so the window sashes do not need to be drilled.
