CANVAS STRETCHING CLAMPS: Our canvas stretching clamps are made of aluminum and feature red rubber handles. The inside of the clamps is made of hard plastic. The clamps have a total length of 20 cm and H12 cm. The clamps are W12 x L3 cm. There is a removable spring between the handles. The clamps will not rust or discolor. STRONG AND TIGHT FRAME CLAMPS: The clamp is robust and grips your canvas with ease. The plastic inside the clamps is grooved to hold your canvas firmly between the clamps. Our clamps grip your canvas frame without tearing or damaging it when stretched on the stretcher frame. They offer both power and precision, making them an essential tool if you work with canvas paintings. RUBBER GRIP: The handles of the clamps have a good grip. They are comfortable and do not hurt your hands or wrists. Perfect for artists suffering from arthritis. The handles are ergonomic and fit the shape of the hand. To make them easier to use, the handles have a spring. Ideal for very large canvas fabrics, as you can stretch the canvas faster and with less effort. IMPORTANT FOR ARTISTS: Our clamps are perfect for attaching thick, thin, large, and small canvas fabrics to a canvas frame. Remove an old painting from a stretched canvas, for example. They hold your canvas without damaging or peeling off the edges. Use them with a screen, needlepoint, ribbon, leather, and vinyl materials. They are used to repair upholstery on chairs or cars.
