Be sure your wall hanger is set just the right depth so the corner studs sit flat against the wall. I didn't like the hanging system but I really can't figure any better way to do it. I used this to hold a certificate in a larger solid Walnut panel. the 3D effect is very classy.
I use this to display an 81/2" x 11" Wolf Adoption Certificate on a wall. Because the whole hanger is clear with no frame the picture of the wolf is enhanced and looks beautiful. The metal pegs at the four corners ensure an even hang and prevent the hanger from scratching the wall. It s a different look; I like it others may not. This hanger is for a thin item not a matted picture.
