Abstract:

A rigid non-expandable frame for holding an artist's canvas or the like, has permanently coupled thereto a plurality of independently operable clamps. The clamps have guides adapted to slide along the frame and include adjustable jaws for grasping the canvas. Each clamp includes a manually operable member with one end positioned against the frame for moving the clamp inward of the frame to selectively permit localized stretching and contraction of the canvas.
