A tensioning system for a sign mounted to frame, such as a billboard sign. A single tensioning cable is provided, having a plurality of movable hooks positioned at various intervals therealong. The cable is confined by pulleys attached to the frame and extends along one horizontal portion of the frame, then along one vertical portion of the frame, to one or more tensioning winches. The movable hooks are engaged with the rods along a corresponding horizontal and vertical edge of the sign. The opposite horizontal and vertical edges of the sign are affixed by stationary or fixed hooks to the frame. By tightening the cable with the tensioning winch or winches, the cable is pulled taut along the one horizontal and one vertical edge of the sign. There is no need for separate tensioning belts and devices, which are replaced by a single tensioning cable.
