I couldn't use the other commercially available racks that are installed on a cabinet or close door so I looked around and found these. I bought two of them and love them. They are a little too narrow to put two jars side by side but can stagger them so that you can get about 16-18 spice jars on each one so I have at reach a way to see where each spice is and get it quickly - most importantly my cabinets are NEAT!! These are a really great organization tool.
