I thought this knob would be good for my laundry door. It is just a laundry closet so I don't need an interior knob. However you need a back to attach the knob which it doesn't have so there was no way to actually attach this knob. If you need just the knob go with the "passage" in the same style. They work great! Otherwise I love the style, color and construction. I bought two other types of this exact knob and absolutely love them!
