Abstract
An integrally moulded device for applying pressure to screen material or a retaining bead, to force same into a groove of a frame member is disclosed. The tool has a central body graspable by the human hand and a thin blade member at each end, each blade member having a straight edge surface extending from the body and a convexly arcuate edge surface extending from the outer end of the straight edge surface back to the body. One arcuate edge surface is transversely rounded for preforming screen material into the groove. The other arcuate edge surface is transversely V-shaped for pushing a flexible bead into the groove to retain the screen material therein. The shape of the blade members permits the application of pressure completely into corners defined by abutting grooves.
