Canvases 18” and below get a 2” Nailess Sawtooth hanger. Any canvas above 18” get heavy duty D-rings and picture wire. At CanvasHQ, we’re all about making the whole canvas artwork experience simple and friendly. That’s why we even include the wall mounting hook with your canvas. These hooks are similar to the Gorilla Hooks that you may have seen on TV. They are certified to hold up to 80 pounds. The best part is that they don’t require any tools to use – no hammer required.
