A merchandise security system includes a rail adapted to be secured to a first associated merchandising structure, which can be a shelf or a wire rack display. The rail includes a first longitudinally extending channel. At least one tile is mounted to the rail. The at least one tile extends away from the rail so as to approach a second associated merchandising structure spaced from the first associated merchandising structure. The at least one tile includes a protrusion which is accommodated in the first rail channel to enable a sliding movement of the tile in relation to the rail. This construction allows selective access to any desired portion of at least one of the first and second associated merchandising structures.
