ABSTRACT:
A sign which includes a sign cabinet having a rigid frame on which a flexible vinyl sign face is stretched. The sign face has hems on its top and bottom edges. Rigid rods are inserted in the hems, and tension springs are extended through notches in the hems and hooked to the rods. The other ends of the springs are hooked on lips projecting from extrusions which extend along the top and bottom of the face frame. The springs hold the sign face taut on the sign cabinet frame. A special hinged end section is pivoted on the frame to permit the sign face to be placed under the proper lateral tension as a result of the lever action resulting from swinging the hinged section inwardly and then bolting it in place on the sign cabinet frame.
