The sign frame is great for end caps and bulk displays and for more stability can be used beneath product containers. This black holder is a high impact styrene plastic that is 7/16 inch thick with mitered style edges. The sign frame is 5 1/2 x 3 1/2 (W x H) with a 4 inch (H) stem on a 4 1/2 x 5 1/2 inch shovel base. This kit is simple to put together and the cards slide easily into the slot opening. The sign frame gives you more signage options since it can be used both horizontally or vertically.
