When to use
- Shipping rigid goods that fit 20x20x40 inches (L x W x H).
- Orders where dimensional weight matters — this size avoids wasted cube.
- Bulk case packs for 3PLs, Amazon FBM, and DTC fulfillment lines.
When not to use
- Goods significantly smaller than 20x20x40 — you pay for wasted void.
- Items over 50 lb — step up to ECT-44 or ECT-48 double-wall.
