The food in your refrigerator can be very important to your survival in the days following an earthquake. As well as securing your refrigerator to the wall with our Refrigerator Strap, you might consider the Refrigerator Door Strap to keep doors closed and prevent food from spilling out. This is also a handy way to keep small children out of the refrigerator. The VELCRO door straps used are rated for 10,000 cycles. They are easy to open and close, yet strong enough to keep the door from swinging open. Each kit contains two door straps.
