Preventing children from falling from windows

There are regular reports in the media of children and toddlers tragically falling from windows. These horror stories should therefore always push us to make sure our own households have the maximum child safety possible. The same applies for all childcare facilities. Under no circumstances should anything be put in front of a window, a balcony or patio doors that the child might climb, including chairs, beds, shelves, etc. Children all too often reach the window sill or window handle from furniture placed near windows. If a child can then hang out of a window or over a railing, there’s a huge risk of falling.

Fast installation and secure application

No drilling, screwing or gluing - windows and doors remain undamaged!

To quickly and easily install the ISI SAFE child safety device, no drilling, screwing or gluing is required. ISI SAFE can be installed on almost all standard windows and doors. No tools are required for this. The patented system is installed in just a few steps and also offers TÜV-tested protection. Thus, ISI SAFE differs significantly from the expensive-to-install solutions currently available on the market.

The ISI SAFE child safety device leaves no damage or annoying adhesive residues on windows, doors and frames. This is a huge advantage, especially for rented properties, as you generally cannot drill or screw either the window or the frame in such residential properties.
