The Camco Fridge Door Block holds your fridge and freezer door open during storage to promote airflow and prevent mildew and odors, and also prevents the door from swinging open if your RV or trailer is uneven. The unique drawstring design adjusts to accommodate doors thick and thin. A high strength neodymium magnet attaches to the inside of the fridge to hold the block in place, and the drawstring can tighten to the thickness of the door, holding the door open but preventing it from opening further. When you’re not using the Fridge Door Block, stick it to the outside of your refrigerator so that you don’t lose it.
