Sturdy and Tight Frame Clamp: This clamp is sturdy and can easily hold your canvas. The plastic interior of the clips has grooves that securely hold the canvas between the clips. As the canvas is stretched on the frame, our clamps fit snugly around the canvas frame without tearing or damaging the canvas. They provide power and precision, making them an essential tool if you are working with canvas painting. Rubber Handle: The handle of the stretcher has a good grip. They are comfortable and will not hurt your hands or wrists. Ideal for artists with arthritis. The handle is ergonomic and fits the shape of your hand. To make them easier to use, there is a spring on the handle. Ideal for very large canvases because you can stretch the canvas faster and with less effort. A must-have for artists: our clips are perfect for securing thick, thin, large and small canvases to canvas frames. For example, take an old painting on a stretched canvas. They hold the canvas in place without damaging or peeling the edges. Use them with screen, embroidery, webbing, leather and vinyl. They are used to repair the upholstery of chairs or cars. Attach the diamond frame to the canvas and attach the art number.
