Common questions
Do I need to buy inner and outer boxes separately?
Yes. This SKU is the outer box only. You must also order the T48638INHD inner box to create a complete, functioning telescoping carton set. Both are required for assembly and use.
What is ECT-44 and why does it matter for stacking?
ECT (Edge Crush Test) 44 means the corrugated can withstand 44 pounds of force per linear inch when compressed edge-wise. This rating supports 4 - 5 tier stacking on pallets, critical for warehouse density and freight efficiency. Higher ECT ratings reduce crush-through during multi-tier loads.
How do telescoping boxes save money on freight?
Telescoping boxes compress flat for storage and ship, then adjust to the exact height needed for each product. This eliminates over-sizing and dimensional weight surcharges, you pay only for space actually used. Reduces inventory SKUs for variable-height items.
What does 'full overlap bottom' mean and why is it important?
Full overlap (FOL) means all bottom flaps extend across the entire carton base, with the outer flaps fully covering inner flaps. This design creates maximum stacking strength and prevents bottom separation under heavy loads, essential for multi-tier palletized shipments and long-distance transit.
