Abstract: A paper roll holder has a paper roll enclosure for rigid partially embedded mounting of the paper roll enclosure into an aperture in a vertical wall, the aperture in a vertical wall defining an upper edge and opposed lower edge in the wall, a releasable cover for releasable mating onto an exposed front face of the paper roll enclosure, the paper roll enclosure having an opposed pair of generally vertical side walls, a lower trough extending laterally between the sidewalls for receiving a paper roll therein, the lower trough having a generally horizontal front lip extending laterally between the side walls, a channel extending downwardly from an undersurface of the lower trough for releasable mating of the channel over the lower edge in the wall, an upper mounting flange extending generally parallel to the channel and extending generally perpendicularly between, and generally upwardly from, the side walls, a rear wall extending upwardly and forwardly from a laterally extending rear-most extremity of the trough

Abstract: A front-loading interlocking modular merchandising display has a bin having front, rear and side surfaces, the front surface having an opening therein, the side and rear surfaces having at least one vertical groove on each of the surfaces, and a rail for sliding engagement within the at least one vertical groove, the rail having, in cross-section, opposed ends wider than a middle section of the cross-section, wherein each of the at least one vertical groove has a front aperture and a recessed cavity behind the aperture, the recessed cavity wider in cross-section than the front aperture, the rail for interlocking mating engagement of two of the bins when the bins are adjacent.
