The new framing system for signs provides a method of stretching the flexible sign material across the opening of a frame. The tensional devices are installed manually from the outside of the sign at regular spacings on the edges of the flexible sign material. The tensional devices are installed by closing the device on, and by the same movement, puncturing retaining holes on the edges of the flexible sign material. The adjustment of the tension of the flexible sign material is done by pushing inwardly on each tensional device to engage it onto a series of serrations inside a slot facing outwardly along the edges of the frame. The outside edges of the frame are held rigid with frame members extending from the bottom of the sign, and thus eliminating the need for support members, between the flexible sign material and the lamps, which normally transmit shadows to the face of the sign. The new framing system can be re-opened for maintenance purposes using a slot type blade screw- driver to pry the tensional devices out of the serrations. The tensional devices and the slot on the periphery of the sign are covered by a cap which locks in place on mating lips, and which can be removed manually by twisting it inwardly along its length.
