A vertical extension adds height to these “periscope” Scan Hooks resulting in extra display area above the top of the gondola. Separate plastic straight-entry backplates allow for easy installation, even though there is no benefit from the straight-entry aspect. Standard hook-mounted label strip front the display. Almost everything about this design is “stock,” merely combined in a new way to provide a “custom-from-stock” solution. Work with a competent  manufacturer to develop low-cost “custom from stock” solutions like this through their in-house engineering department and knowledge of “stock” components commonly available.
