The BSC PREFERRED 321818 is a corrugated bulk cargo box designed for industrial shipping and storage applications. Sold in a pack of 15, these boxes ship and store flat, reducing warehouse footprint and handling time between uses. Built to the dimensions professionals expect for bulk freight applications, each box measures 37 inches in length, 50.25 inches in width, and 4.75 inches in height. The flat-pack design is a standard in commercial shipping operations, making these a practical choice for facilities that move high volumes of product on pallets or freight carriers.
These corrugated boxes are suited for warehouse operations, distribution centers, and freight consolidation environments. The bulk cargo box format is commonly used in manufacturing, wholesale distribution, and logistics settings where large or irregularly shaped items need a sturdy, flat-pack-capable outer container. The pack-of-15 quantity per unit of purchase is appropriate for operations that maintain ongoing shipping activity and need consistent box supply on hand.
Listed as equivalent to part number S-18380. Designed as a standard bulk cargo corrugated box suitable for general industrial shipping and storage applications.
Assembly of corrugated bulk cargo boxes typically requires no tools beyond tape or strapping equipment. Ensure the box is fully squared and bottom flaps are properly secured before loading cargo. Do not exceed the rated load capacity of the box. Store flat in a dry environment to preserve structural integrity prior to use.
