These safety bars are real great! They provide optimum all-round protection for my little treasure. Cabinets and drawers can now no longer be open and the fingers are not pinched when this experiment by simply pressing again to close. The lock can be opened by the parents by simple push. If you leave the door open and her child trying to close them, we likewise Duch the latch prevents to again prevent the crushing fingers. Parents push the latch down quickly for the door can be closed easily! So pure safety and very simple for adults! A bit of tact and precision you need for installation, but for all who screwed together the nursery itself well this should not be a problem.
