Sk8ology Deck Displays are the original floating gallery display hanger. Made from clear polycarbonite with stainless steel hardware and guaranteed for life. Sk8ology's simple one screw/drywall anchor installation means your walls don't need multiple holes put in them to hang each board. Sk8ology Displays feature two types of installation options - locked or easy on/easy off depending on your individual situation. (To hang a board horizontally you will need two Sk8ology Deck Displays.)
