A multi-component divider including a first divider component and a connection mechanism for a second divider component. The second divider component connects to the first divider component when the first divider component is connected to a base. The second divider component extends above the first divider component, thereby extending the overall height of the divider. The base and multi-component divider can be used in locations where there is limited space between shelves, such as a shelf in a freezer or refrigerated display, or in any application where a higher divider may be preferred, but cannot be installed. The base can additionally include a pusher moveable along a longitudinal direction of the base, wherein the pusher is also adjustable linearly along a direction perpendicular to the longitudinal direction of the base.
