Use Command Canvas Hanger to hang your canvas pictures across your wall. Simply apply the Canvas Hanger to your wall, place the picture on it and you are done. The small sawtooth ridge grips into the canvas frame or stretcher bar, providing extra grip and security. If you need to move or take down your pictures, the hanger removes cleanly with no nail holes or sticky residue. It will hold strongly to a variety of surfaces including solid, hollow and painted walls.
