ABSTRACT:
A double face sign utilizes flexible sign face material which is tensioned to a sufficiently high degree of absorb all loads anticipated for the sign. A relatively light weight and weak cover frame is provided to which the sign face is pretensioned. The more rigid and strong main frame of the sign carries a tensioning edge which extends outwardly of a face plane of the main frame. The cover frame is bolted against the face plane of the main frame to press the inner surface of the sign face against the tensioning edge, to complete tensioning of the sign face material. The final tensioning force is absorbed by the strong main frame by its attachments to the cover frame.
