Adjustable Shelf Lighting System | Shelving units with adjustable shelves that will light up in any position where they are placed…the ‘magic’ of EssentialEdge. Each shelving unit requires two busbars to be installed on each side of the unit; busbars are needed only for sections of the unit where illuminated shelves are desired. After installation, busbars can be covered by laminate or veneer, or concealed by adjacent cabinetry. Each adjustable shelf requires two (2) Brass Contact Pads and two (2) Brass Shelf Brackets. Two (2) Lug Ring Connectors are required to connect driver to busbars.
