Space saving manual shelf management system

A bottom supporting shelf allocation and management system for allocating shelf space among rows of products, the system comprising:

• a plurality of adjacent shelf allocating and managing units, each unit associated with at least one row of products, wherein each unit includes
• a) a base substantially corresponding in length to a depth of a shelf where the base is adapted to rest on the shelf and to support the at least one row of products,
• b) an integral perpendicular side divider coupled to the base and extending substantially the same length as the base, wherein the side divider extends vertically above the base and is attached to the side edge of the base and wherein the coupling of the base and side divider prevents movement of the side divider in relation to the base, and wherein an uppermost surface on a side of the base opposite the side of the base to which the side divider is coupled is lower than a top surface of the side divider,
• c) a puller that travels in a channel on an upper surface of the base and along the length of the base, a backstop attached to the rear of the puller and extending laterally across a portion of the upper surface of the base which is configured, when the puller is manually drawn forward, to make contact with a rearmost product resting on the base and push the rearmost product and any other products on the base forward, wherein the channel includes overhanging locking rails configured to allow forward and backward movement of the puller in the channel and configured to prevent upward movement of puller.
