For situations where the persistent person with dementia is at risk of attempting to forcibly enter the refrigerator, this Heavy-duty Refrigerator Lock bonds (3" x 2") steel plates to your refrigerator side and door with high-strength, self-adhesive pads. Once installed, they are securely in place. Plastic-coated steel cables accept a small pad lock (included). When locked the refrigerator door cannot be opened. When no lock is in place the doors operate normally.
