The 30 x 20 x 20 inch heavy-duty multi-depth box is built from ECT-44 single wall kraft corrugated, delivering approximately 40% greater stacking strength than standard ECT-32 containers. Pre-scored side panels allow the height to be cut down to multiple depth intervals, consolidating several box sizes into one and reducing dead air space in each shipment. Note that a cutting tool is required at the scored corners to resize the box.

This design is well suited for e-commerce fulfillment centers, retail distribution, and manufacturing shipping lines where product heights vary across orders. Right-sizing a carton at the pack station without stocking a separate box for every product height reduces storage footprint and material waste — a practical advantage in high-SKU environments.

Interior height measures 20" at maximum depth, and each box weighs approximately 3.258 lbs. Boxes are sold in bundles of 10 and ship via parcel carrier.
