Command Canvas Picture Hangers make hanging your canvas prints, paintings and decorations quick and easy. Once the Canvas Hanger is applied to your wall, simply place your canvas picture on the canvas hanger and you are done. The small sawtooth ridge on the canvas hanger grips into the canvas frame, or stretcher bar, providing extra grip and security. Best of all, when you are ready to take down or move your canvas pictures, they come off cleanly - no nail holes or sticky residue. Command Canvas Picture Hangers are available in size large which holds most canvas pictures up to 18 in. x 24 in. and 3 lbs. and size jumbo which hold most canvas pictures up to 24 in. x 36 in. and 5 lbs.
