|Metalcraft's Wavy Wrap-Around Post & Panel Sign Brackets allow you to create post and panel systems using your own flat panel sign faces. Simply slide the aluminum bracket over the 3" diameter round pole. The sign face is sandwiched inside the bracket. A secure connection is made by bolting through the bracket and sign face. A self-tapping screw is then used to set the bracket height, connecting it to the pole at the desired height.
