Canvas Spring Clips have a curved shape and exert enough pressure to hold your canvas securely in place in the frame.
Price per pack.
For a floater frame format the clips need to be fixed to the canvas itself so that the frame is then pinned in place behind the canvas. For a non-floater format they are fixed to the frame to pin the canvas in place.
