Your Canvas Wrap Pro comes with pre-installed hanging hardware in the form of sawtooth hangers. If you need to install wire hanging hardware for gallery installation, we recommend ordering a Traditionally-Stretched Canvas Wrap to easily screw in D-rings and install wire. We cannot be held responsible for changes or enhancements that you make to your canvas. Canvases that have been damaged through the addition of hanging hardware are not eligible for return or replacement. Do not install a wire hanging kit by attaching the wire to the pre-installed sawtooth hanger on the Solid-Faced Canvas Wrap.
