Common questions
Do I need to buy both inner and outer boxes separately?
Yes. The T4472INNER telescoping inner box must be paired with the T4472OUTER box to create the complete two-piece adjustable system. Both components are sold separately as bundles of 25 to match your volume needs and reduce packaging redundancy.
What ECT rating provides and why does ECT-32 matter for tall boxes?
ECT-32 (Edge Crush Test 32 lbs/inch) delivers robust stacking strength essential for tall cartons subject to compression during storage and transit. This rating ensures your 72" boxes maintain structural integrity under multi-layer pallet loads, protecting product while reducing damage claims.
How much height adjustment does the telescoping design provide?
The two-piece telescoping construction allows the inner box to nest within the outer box, enabling adjustable compression to accommodate product heights within the full 72" dimension while maintaining crush resistance and professional appearance, ideal for items ranging from 48" to 72" tall.
Will these boxes reduce my dimensional weight shipping costs?
Yes. By adjusting telescoping height to match actual product dimensions, you eliminate excess void space that carriers use for DIM weight calculations. This precision fit directly lowers per-unit freight spend compared to standard fixed-height boxes oversized for variable items.
