Abstract
A device for stretching a canvas mounted to a frame comprises a spacer and a screw. The frame has a plurality of side members each mutually abutting at angled ends. A first portion of the spacer includes a central aperture therethrough and two opposing ends or sides. Each end of the first portion is sized to engage a contact surface of each side member. The screw has a threaded shaft adapted for rotational engagement with the central aperture of the first portion of the spacer. The threaded shaft terminates at a first end thereof with a screw head that has a frustoconical side wall and an end surface that includes a tool-engaging recess. Rotating the screw to move the screw head closer to the spacer causes the spacer to push the side members mutually away from each other to stretch the canvas.
