Secure & storm proof your home using GMI®’s Hurricane Wedge®. The GMI® Hurricane Wedge® holds your plywood sheets securely in place during a Class 2 Hurricane (typical post-landfall wind speeds) protecting your windows and your belongings inside your home or business. Comes in packages of 2. We recommend 16 packages to secure an average home with 16 windows. The GMI® Hurricane Wedge® was tested by the University of New Orleans, Department of Civil and Environmental Engineering to assist in providing adequate protection to a Class 2 Hurricane. Also, we have the GMI® Hurricane Wedge® Extension Kit for use with two sets of Hurricane Wedges when installing in windows measuring 48"-72". This allows 2 standard units to be coupled together.
