An integrated “T” assembly (500) combines into a single integrated assembly, a track portion along both sides of a divider (504). The T assembly may have a wide-base portion (518), which may include a spring-urged-pusher track, on one side of the divider and a narrow-base portion (520) on the opposite side of the divider. An offset pusher (700) may have an upper portion that is offset, via an angled offset portion, from a lower portion of the pusher. Additional supporting bases, any of which may include spring-urged-pusher tracks and / or a spring-urged pusher, may be used under a wide product. Left and right side finisher (600) components may be paired with T assemblies near the sides of a merchandise-display shelf. The T assembly, base, and / or end finishers may be coupled to a front rail via a complimentary tongue and groove arrangement and / or a non-slidable engagement, such as mating teeth.
