Abstract: A display device is provided which may be used to display surfboard fins and related product literature. In one example, a display device includes a plurality of tubes and machined parts which may be assembled and configured as further disclosed herein. Such a display device may be used, for example, to hold and secure surfboard fins to facilitate display of the fins and permit the handling of the fins by consumers. Advantageously, the display device may also be implemented to prevent the fins from being completely detached from the display device without the use of an appropriate security device. The display device may also be implemented to hold and secure information (e.g., product literature) associated with the fins.
