With the new "WinLock" reer window safety device, kids don't even have to risk opening a window by themselves. It is neither screwed nor glued, but fixed between the handle and the frame with a few simple movements.

The WinLock is a simple and easy to use device.

Two independent movements prevent children from opening the lock: by pressing the lock button and simultaneously turning the window handle, the security device can be unlocked.

The window and balcony door lock is not only easy to use, it is also easy to install - without any drilling or gluing. It can be inserted between the handle and the window or balcony door frame with a few simple steps and removed if necessary without leaving any residue.

It's easy to install and easy to clean.
