Hinge Handles for A-frame signs (also called sandwich board signs) provide an ingenious hinge for custom-sized sign faces. Built with a metal rod surrounded by plastic sleeve and tabs, they are super-strong, rust resistant, easy to install, and very inexpensive. These hinge handles allow 360° rotation, providing four sign faces. Like all A-frames, these hinge handles produce a stable sign that can be folded flat easy storage. These hinge handles come in 12" and 16" widths. Complete your sign with sturdy Sign Feet for A-Frames.
