With the slide lock, you can secure cabinets and refrigerators with double doors so your little one doesn't get his fingers stuck. The latch fits 55mm doors and is easy to mount. The sliding latch comes in 100% biodegradable, Cradle to Cradle certified packaging. This means that the packaging will decompose naturally once you throw it away and will not leave anything behind that can harm our planet. In this way, you protect your little one from accidents and take responsibility for the environment in which it grows up.
