Longer runs want fewer, longer shelves — more facings per shelf, fewer brackets per run. At 48 inches, this steel shelf carries a wide spread of impulse merchandise with the same enclosing sides that keep candy, gum, batteries, and travel items in place as shoppers pass. It inserts into standard slatwall grooves and repositions without tools, serving a shop wall or checkout display as readily as NeXtrac panels, end caps, and gondolas. Where a display narrows, the 24-inch shelf continues the same format at half the length, so one shelf family covers the full run.
