Common questions
Do I need to purchase inner and outer boxes separately?
Yes. The T8848OUTERDW outer carton must be paired with the T8848INNERDW inner carton to create a functional telescoping set. This two-piece design allows height adjustment while maintaining structural integrity. Order both SKUs to ensure complete packaging capability.
What is ECT-48 and why does it matter for stacking?
ECT (Edge Crush Test) -48 measures 48 lbs per inch of edge crush strength, exceeding many single-wall alternatives. Double wall construction doubles durability, enabling safe stacking of 2 - 3 pallet tiers and protecting goods during conveyor automation and long-haul freight.
Can these boxes be used for both light and heavy items?
Yes, ECT-48 double wall kraft is rated for items up to 65 lbs per box, depending on stack height and duration. The FOL (full overlap) bottom adds 15 - 20% additional strength, making them suitable for electronics, machinery parts, industrial tools, and dense products.
How much can I save by switching to telescoping boxes?
Telescoping designs reduce SKU proliferation by 30 - 40% for businesses shipping mixed heights, lowering inventory carrying costs and warehouse floor space. By shipping flat-nested, you also reduce dimensional weight charges by up to 25% compared to fixed-height alternatives on parcel carriers.
