The HangZ™ 15lb Canvas Flat Mount Sawtooth Hooks are specifically crafted to seamlessly integrate with HangZ™ sawtooth hangers. The unique HangZ™ design addresses the common issue of unsightly views created by traditional hooks when hanging artworks with Sawtooth hangers. With these hooks, you'll never see the hook again, providing a clean and aesthetically pleasing display. These hooks are particularly well-suited for canvases and open-back frames, offering an ideal solution for showcasing your artwork. For optimal results, it is recommended to use them in conjunction with HangZ Sawtooth Hanger models #20000 and #20001.
