What is the primary purpose of wood-cleated panelboard boxes?

The primary purpose of wood-cleated panelboard boxes is specifically designed to handle heavy or bulky loads. These boxes are constructed to provide enhanced strength and support, making them ideal for shipping items that are either large or significantly heavy. The wood cleats reinforce the structure, adding extra durability and stability, which is crucial when transporting substantial weights. This design minimizes the risk of damage during handling and transport, ensuring the contents remain protected. In contrast, options like holding liquids, shipping lightweight items, or accommodating fragile items do not align with the specific engineering and intended use of wood-cleated panelboard boxes.
