These 11 1/2 x 11 1/2 x 15 3/8 inch double wall corrugated boxes are built to ECT-48 double wall specification, delivering measurably greater puncture resistance, compression strength, and stacking performance than standard single wall cartons. The added wall mass makes these a practical upgrade wherever product weight, stacking height, or transit stress would push a single wall box to its limits.

The near-square footprint and 15 3/8 inch depth make these boxes well matched for dense manufactured components, bottled or jarred goods, automotive parts, and industrial hardware. They are equally at home in high-volume distribution centers, manufacturing shipping docks, and retail backroom operations where reliable stacking under load is a daily requirement.

Each box ships flat, reducing staging space and simplifying pallet builds. At approximately 1.742 lbs, the boxes add meaningful structural mass without excessive tare weight. Bundles of 25 are available for parcel delivery, allowing facilities to order in quantities suited to their throughput.
