Wunderbars stretcher bars offer a unique solution to canvas stretching and canvas framing. Our patented spring loaded stretcher bars keep tension across the canvas frame no matter the humidity. Our Switch Frame range makes framing your stretched canvas frame simple. Easily slide out a canvas print from the frame and replace with a new one in minutes. Wunderbars stretcher bars save you time and money with all of our canvas stretching products. For traditional stretcher bars we also offer a bespoke stretcher bar service where we make the stretcher frame to your personal requirements, down to the nearest millimeter. And to finish, why not take a look at our canvas hanging solutions. All of our hangers allow the frame to be flush against the wall.
