An anti-tip device is a metal bracket that is designed to prevent a product, especially one that is top-heavy--from tipping over. It attaches to the product and secures it against the wall. An anti-tip bracket is included with all gas dual fuel and electric ranges as well as most built-in and counter-depth refrigerators. It is a safety device and must be attached when the appliance is installed. The installation instructions for the appliance provide directions for installing the anti-tip. If you make an appliance purchase through our site or through a retail partner and have the appliance delivered and installed the delivery agent is required to install it with the anti-tip bracket.
