Common questions

Do I need both inner and outer boxes?
Yes. The T12448INNER (this product) must be combined with the T12448OUTER to create a functional two-piece telescoping box set. Purchase both SKUs separately and match quantities to your needs.
What ECT rating means for my stacking operations?
ECT-32 indicates the box can handle 32 ECT (edge crush test) rating, providing reliable stacking strength for mid-weight products in typical warehouse conditions. It's ideal for general industrial shipping without requiring heavy-duty reinforcement.
How much can I adjust the height of these boxes?
The telescoping two-piece design allows you to nest and extend the inner box within the outer box, accommodating varying product heights. This eliminates the need for multiple box sizes, reducing SKU complexity and storage costs.
How does this improve freight efficiency?
By adjusting box height to your product, you minimize void space and reduce dimensional weight charges on shipments. This directly lowers per-unit freight costs and maximizes trailer or container utilization, especially valuable for tall, lightweight items.
