An integrated shelf allocation management system for allocating space among rows of products comprising: a first component comprising a base, at least two side walls, and a barrier element, wherein said base is disposed along a longitudinal axis, wherein said at least two side walls are located on opposing edges of said base and extend vertically from said base such that said base and said side walls form an integrated unit, and wherein said barrier element is located at a front end of said first component, said base further comprising a first track and a second track located on said base, wherein said first track and said second track are each spaced from one of said side walls and are disposed along a longitudinal axis, further wherein said first track and said second track define a central channel in said base; a second component comprising a base, at least two side walls, and a barrier element, wherein such base runs along said longitudinal axis, wherein said at least two side walls are located on opposing edges of said base and extend vertically from said base such that said base and said side walls form an integrated unit, and wherein said barrier element is located at a rear end of said second component, wherein said second component is adapted to telescopically engage a rear portion of said first component to form an integrated assembly, wherein said integrated assembly is adjustable along said longitudinal axis and is further adjustable in a direction along an orthogonal axis to accommodate products of varying widths; and a backstop assembly positioned between said side walls, said backstop assembly comprising a backstop base and a back plate located at a rear end of said backstop base, wherein said backstop base is positioned in said central channel of said integrated shelving allocation management system, further wherein said backstop base includes a central backstop channel that runs longitudinally along the backstop base, said central backstop channel includes a lower ledge at a front end of said backstop base, wherein said backstop assembly further comprises a puller member having a longitudinal axis and is adapted to slideably engage said backstop base, wherein said puller member is disposed in said central backstop channel, wherein said puller member comprises at least one tab disposed in a direction transverse to the longitudinal axis of the puller member at a rear end of said puller member, said at least one tab having a width that allows said puller member to engage said lower ledge, wherein said puller member is adapted to disengage from said backstop assembly when said puller member is pushed along the longitudinal direction toward the rear of said system. a first component comprising a base, at least two side walls, and a barrier element, wherein said base is disposed along a longitudinal axis, wherein said at least two side walls are located on opposing edges of said base and extend vertically from said base such that said base and said side walls form an integrated unit, and wherein said barrier element is located at a front end of said first component, said base further comprising a first track and a second track located on said base, wherein said first track and said second track are each spaced from one of said side walls and are disposed along a longitudinal axis, further wherein said first track and said second track define a central channel in said base; a second component comprising a base, at least two side walls, and a barrier element, wherein such base runs along said longitudinal axis, wherein said at least two side walls are located on opposing edges of said base and extend vertically from said base such that said base and said side walls form an integrated unit, and wherein said barrier element is located at a rear end of said second component, wherein said second component is adapted to telescopically engage a rear portion of said first component to form an integrated assembly, wherein said integrated assembly is adjustable along said longitudinal axis and is further adjustable in a direction along an orthogonal axis to accommodate products of varying widths; and a backstop assembly positioned between said side walls, said backstop assembly comprising a backstop base and a back plate located at a rear end of said backstop base, wherein said backstop base is positioned in said central channel of said integrated shelving allocation management system, further wherein said backstop base includes a central backstop channel that runs longitudinally along the backstop base, said central backstop channel includes a lower ledge at a front end of said backstop base, wherein said backstop assembly further comprises a puller member having a longitudinal axis and is adapted to slideably engage said backstop base, wherein said puller member is disposed in said central backstop channel, wherein said puller member comprises at least one tab disposed in a direction transverse to the longitudinal axis of the puller member at a rear end of said puller member, said at least one tab having a width that allows said puller member to engage said lower ledge, wherein said puller member is adapted to disengage from said backstop assembly when said puller member is pushed along the longitudinal direction toward the rear of said system.
