[HIGH QUALITY MATERIAL] - This child baby safety door block is made of high-density EVA foam, which is environmentally friendly, non-toxic, strong and durable. It's designed to protect children from accidental entrapment and can be quickly and easily attached to any door, window, etc. [Perfect Fit] - Child safety door size is 9.3 cm * 9.3 cm * 1.5 cm, the center distance is 3 cm, the mounting opening is 0.7 cm, and the mounting opening can be opened to 5 cm. Fits the door perfectly and won't fall or slide. [Shockproof and Silent] - The foam guard can withstand door jams and strong impacts without deforming. It can effectively prevent children from closing the door in windy weather. Sudden closing of the door absorbs shock and will not damage the door. If the child is sleeping, there will be no sound when the door is suddenly closed, and it will not wake up the sleeping child. [How to use] - Simply place the finger trap on the outside edge of the door, high enough to keep it out of reach of children. You can also place an anti-finger device at the top of the door, at least 6 inches from the edge. When not in use, simply hang it on a door handle or knob. Fits all door sizes. [Wide Use] - The child safety gate can be used not only on doors at home, but also on windows, drawers or classrooms to keep your fingers safe and not accidentally locked in the room. Also great for letting your pet move around the room freely.
