Premium Safety Material: Crafted from high-density EVA foam, this child safety door stopper is eco-friendly, non-toxic, solid, and durable. Specifically designed to protect children from accidental pinches, it attaches quickly and easily to any door, window, etc. Perfect Fit: The child safety door stopper measures 9.3cm * 9.5cm * 1.5cm, with a median distance of 3cm and a mounting opening of 0.7cm that can be expanded up to 5cm. It adapts perfectly to the door, preventing it from falling or sliding. Anti-Shock and Quiet: This protector withstands door impacts and forceful bumps without deforming. It effectively prevents children from slamming doors in windy weather. A sudden door closure absorbs shocks and won't damage the door. When children are sleeping, there will be no noise when the door suddenly closes, preventing them from waking up. Easy to Use: Simply place the pinch guard on the outer edge of the door, high enough to be out of reach of children. You can also place the pinch guard on top of the door, at least 15cm from the edge. When not in use, simply hang it on the handle or doorknob. Fits all door sizes. Wide Application: The child safety barrier can be used not only on the doors in your home but also in windows, drawers, or classrooms to ensure your fingers are safe and not accidentally locked in the room. Also suitable for allowing your pets to move freely in the room.
