Unlike shipping labels, these three-dimensional cones can be seen from all sides, even when operating a forklift. Attach by strapping, shrink-wrapping, or taping to the top of your pallet. Made of cardboard, these visual warnings will crush if something is stacked on them, indicating potential damage. A must-have for anyone working in warehouses or storage facilities, these cones ship flat and are easy to compactly store. Use these four-sided temporary cones to prevent double-stacking of freight orders or during warehouse storage to reduce damage to palleted items. Use for any form of transportation: The Trafford Industrial No Stack Cone are designed to provide the best value crowd management solution for your event space. TrainsTruckSeaAir
