An integrated “T” assembly combines into a single integrated assembly, a track portion along both sides of a divider. The T assembly may have a wide-base portion, which may include a spring-urged-pusher track, on one side of the divider and a narrow-base portion on the opposite side of the divider. An offset pusher 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 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.
