Common questions

Why do I need both inner and outer boxes for this telescoping carton?
The two-piece telescoping design requires both the T6648INNERDW inner box and T6648OUTERDW outer box to function. When nested together, they create a double-wall ECT-48 corrugated structure that provides crush strength, stacking performance, and compression resistance compared to single-wall alternatives.
What products work best in 6x6x48 telescoping boxes?
These boxes excel for tall, narrow items: baseball bats, fishing rods, poster tubes, rolled documents, PVC pipes, fabric bolts, and lightweight columnar products. The adjustable height accommodates varying product lengths from shorter fills to full 48" utilization, eliminating the need for multiple box sizes.
How does ECT-48 double wall compare to other corrugated options?
ECT-48 double wall delivers 48 lbs of edge crush strength, making it suitable for medium-weight loads and multi-tier palletization. The two-layer construction with full overlap bottom provides stacking protection versus single-wall boxes, reducing product damage and insurance claims in high-volume operations.
Can I stack these boxes during storage and shipping?
Yes. The ECT-48 double-wall construction with full overlap bottom design supports vertical stacking for both storage efficiency and pallet optimization. Calculate total weight per stack tier to maximize density while maintaining product protection, ideal for reducing freight class and lowering per-unit shipping costs.
