The inner box (T4448INNER) slides into the outer box (T4448OUTER) to create an adjustable fit. This allows you to customize box height to match product length, reducing void fill waste and dimensional weight charges while maintaining consistent bottom footprint dimensions across shipments.
ECT-32 indicates edge crush test strength of 32 pounds per linear inch, ideal for single-wall corrugated with moderate stacking loads. The full overlap bottom reinforces corner strength, making this box suitable for stacking 3-5 units high in warehouse environments without crush risk.
Both the inner (T4448INNER) and outer (T4448OUTER) boxes are required to create the complete telescoping carton. They are sold separately, so you'll need to order both SKUs to assemble your full packaging solution.
This size excels for tall, narrow items: tubing (PVC, metal, cardboard), handles, rods, poles, rolled textiles, sports equipment, and specialty components. The adjustable height accommodation means you can use one box size for products ranging from 24" to 48" in length, reducing inventory complexity.
