Frequently Asked Questions
The T6672INNER inner box slides inside the T6672OUTER outer box to create an adjustable carton system. This allows you to compress taller shipments into a smaller footprint or accommodate items up to 72" in height, reducing box SKU counts and freight costs across variable product heights.
ECT (Edge Crush Test) 32 measures the corrugated's vertical stacking strength at 32 lbs/linear inch. For 72" tall cartons, ECT-32 ensures adequate burst and crush resistance during multi-level warehouse stacking and transit, preventing top-to-bottom collapse.
Yes. The T6672INNER and T6672OUTER are sold as separate SKUs to allow flexible ordering. You must combine both boxes to create a functioning telescoping set. One inner + one outer = one complete carton system.
Telescoping boxes eliminate multiple box size purchases by accommodating variable heights in a single adjustable system. This reduces inventory holding costs, freight volume waste, and labor associated with selecting the 'right size' box, a critical efficiency gain for high-throughput fulfillment operations.
