H114.4.1 Tensioning Devices

Opposing ends of a fabric sign stretched around the edges of a sign structure may be secured to each other by means of mechanical tensioning devices behind the sign structure, provided that the open ends for the "S" hooks shall be closed with safety clips. Spring snaps may be used in lieu of "S" hooks. The mechanical tensioning devices shall be fastened to safety wires, placed through the holes in the load spreader bars or grommets, to prevent the devices from falling in the event of loss of tension.
