Command outdoor window hooks are perfect for hanging wreaths, signs, thermometers or other seasonal decorations directly to the outside of your window. Using a new formulation of the revolutionary Command adhesive, these outdoor hooks are specially designed to hold strongly outdoors - they are water resistant, UV resistant and can handle temperature extremes from -20 degree Fahrenheit to 125 degree Fahrenheit. And like all Command products, they remove cleanly - with no marks or sticky residue - so you can use them over and over again.
