Swapping a poster takes seconds here. The snap-open aluminum frame flips out on all four sides, the 8.5 by 11 inch sheet drops in behind a clear PVC cover, and the frame closes flat again. Rotation through 360 degrees lets the same holder show portrait or landscape as the message changes. Height runs 32 to 51.5 inches vertically and 30 to 49.5 inches horizontally, so it reads at counter level or across an aisle. The 10-inch weighted base fills with water or sand for stability in a busy entryway, and an anti-slip rubber ring guards polished floors from scratches. At 3.5 lbs the stand carries easily between a shop floor and a trade booth.
